வினுதா செல்லும் வழியை தொடர ஆரம்பித்தான் அபினவ். அவள் வேகம் மிகவும் குறைவாய் இருந்தது. பாவம் ரொம்ப வலிக்குது போலருக்கு.. பாத்து வந்துர்கலாம் என்று வருத்தப்பட்டான். பைக்கில் பின் தொடர்வது கடினம் என்று எண்ணிய அபி பைக்கை சாலை ஓரமாய் நிறுத்தி விட்டு நடக்க ஆரம்பித்தான்.

"எப்படியும் இவ வீடு பக்கத்துல தான் இருக்கும்.. நடந்து தான போறா.. பஸ் ஸ்டாப்ல வெய்ட் பண்ணல.. இவ வீட இன்னிக்கி கண்டு பிடிச்டனும்" என்று எண்ணிக் கொண்டு அவளை தொடர்ந்து ஃபாலோ செய்தான். "ஃபாலோ பண்றத கண்டுபிடிச்டா என்ன பண்றது?" என்ற கேள்வி அவனுள் முளைத்தது. உடனே நண்பன் ஒருவன் கூறிய டைலாக் பொறியில் தட்டியது. "மச்சான், பொண்ணுங்கள ஃபாலோ பண்ரப்ப நம்ம தாண்டா கவல படறோம் அவங்களுக்கு தெரியாம ஃபாலோ பண்ணனும்னு. ஆனா நம்ம மனசுல ஃபாலோ பண்ணனும்னு தோணின உடனேயே அது அவங்களுக்கும் தெரிஞ்சிடும். சும்மா தெரியாத மாதிரி வெட்டி சீன் பொடுவாங்க அவ்ளோதான்".

"ஒரு வேல நம்ம அவ பின்னாடி வந்துட்டு இருக்கறது தெரிஞ்சுர்குமோ... ச ச இருக்காது" என்று யோசித்து கொண்டிருக்கையில், "என்ன மிஸ்டர் உங்களுக்கு வேல வெட்டி எதுவும் இல்லயா.. எதுக்கு இப்பிடி பின்னாடி காணதத கண்டா மாதிரி வரீங்க.. போய் புள்ள குட்டிய படிக்க வெக்கிற வழிய பாருங்க.. போங்க" என்றாள் வினுதா..

"எனக்கு வேல வெட்டிலாம் இல்லங்க.. நான் MBA finance படிச்சுட்டுருக்கேன்.. also எனக்கு புள்ள குட்டியும் இல்ல.. அழகான பொண்ணா தேடிட்டு இருக்கேன் to get புள்ள குட்டி" என்று சற்று நக்கலாய் பதிலளித்தான். "ஜோக் அடிகர்தா நெனப்பு.. போய்யா வேலய பாத்துட்டு.. யாரு கேட்டா உன் பயோ-டேட்டா.. ஹ்ம்ம்ம்" என்று சொல்லி விட்டு அழகாய் இதழ்களை இரு முறை கோணிக்கொண்டாள்.

"இல்லங்க இது பயோ-டேட்டா இல்ல.. நீங்க கேட்ட கேள்விக்கு பதில்.. பயோ-டேட்டானா பேரு இருக்கும்ல.. i forgot to say my name.. நான் அபினவ்.. நீங்க"..

"அதான் ஏரியாக்கு 10 friends வெச்சு இருப்பீங்களே பொண்ணுங்க பேரு அட்ரெஸ் போன் நம்பர்லாம் கண்டுபிடிக்க.. அந்த நிபுணர் குழு கிட்ட சொல்லி கண்டுபிடிக்க சொல்லு" என்று அந்த இடத்தை விட்டு நகர்ந்தாள்..

"இது நக்கல் நையாண்டி மண்ட கணம் பிடிச்ச பார்ட்டியா இருக்கும் போலருக்கே.. அபி விடாதடா அவள" என்று தனக்குள் கூறிக் கொண்டு தொடர்ந்து அவளை ஃபாலோ செய்தான்..
ஒரு 15 நிமிடம் நடந்திருப்பாள் வினுதா.. அபியும் அவளை பின் தொடர்ந்து வந்திருந்தான். ஒரு அழகிய சிறு வீட்டிற்குள் நுழைந்தாள்.. சங்கீத சத்தம் இனிமையாய் கேட்டு கொண்டிருந்தது அந்த வீட்டிலிருந்து.. "ஆயாயோ இது தா தா ரி நா பார்ட்டி போலருக்கே" என்று அங்கலாய்த்துக் கொண்டான். "சரி கொஞ்ச நேரம் கேட்டு தான் பாப்போம்" என்று எண்ணி அங்கேயே நின்றான்.

"சமயாநிக்கி தகு மாதலாடனே பா மகரிரி" என்று மெல்ல அந்த சங்கீதத்தில் வினுதாவின் குரலும் இணைந்து, இசையை மேலும் இனிமை ஆக்கியது.

வினுதா செல்லும் வழியையே வெறித்து பார்த்து கண்ணீர் சிந்திக் கொண்டிருந்தான் அபினவ். சுமார் 5 நிமிடங்கள் கடந்திருக்கும். மெல்லமெல்ல அவன் கண்ணீர் வறண்டு போக தொடங்கியது. இயல்பு நிலைக்கு திரும்பியவனாய் கடல் அலைகளின் பக்கம் கவனத்தைதிருப்பினான். கண்கள் மட்டுமே அவன் நினைத்ததை செய்தன அனால் மனமோ இன்னமும் வினுதா சென்ற திசை நோக்கி பறந்துகொண்டிருந்தது.

ஒளியினும் வேகமாய் பயணிக்க கூடிய ஒன்று உண்டெனில் அது மனித மனமே . நொடியில் பல்லாண்டுகள் பின்னோக்கி உருளும். சமயம் பார்த்து பல ஆண்டுகள் கழித்து நடக்கப்போவதை கற்பனை செய்யும். ஆனால் அது கடந்த காலத்தை நோக்கிப்  பயணித்தாலும்எதிர் காலத்தை கற்பனை செய்தாலும், நிகழ் காலத்தில் அதன் நிலை துயரமாகத்தான் இருக்க வேண்டும். மகிழ்ச்சியாய் இருக்கும் சமயம்மனம் கடந்த கால நினைவுகளை அசை போடுவதில்லை. அபினவின் மனமும் வேகமாய் பயணித்தது.

சுமார் ஒன்றரை ஆண்டுகளுக்கு முன்பு...

எத்திராஜ் கல்லூரி வளாகம்..

ரம்பை ஊர்வசி மேனகை போன்ற பெண்களை இங்கு பலர் தேடி ஏமாந்து போனாலும் சிலருக்கு அதிர்ஷ்டம் அடிக்கத்தான் செய்கிறது.. அப்படிப்பட்ட அபூர்வமான அதிர்ஷ்டசாளிகளில் அபினவும் ஒருவன்..

அபினவ் மனம் முழுதும் ஸ்பென்சர்இல் .. லயோலா b - school இல் முதல் ஆண்டு சேர்ந்து சரியாய் 4 வாரங்கள் தான் ஓடியிருக்கும்.. வகுப்புகள் வழக்கம் போல் அலுக்க ஆரம்பித்தன. நண்பனிடம் இருந்து sms "மச்சி ஸ்பென்சர்ல இருக்கேன் கிளாஸ் முடிஞ்சதும்வந்துடு".. விக்கியின் sms இருந்த கொஞ்ச நஞ்ச ஆர்வத்திலும் மண் அள்ளி போட்டது.

கல்லூரி முடிந்ததும் நேரே நெரிசல் மிகு கல்லூரி சாலையில் 40 களிலும் 20 களிலும் மாறி மாறி pulsar ஐ முறுக்கினான். எத்திராஜ்கல்லூரி நெருங்கியவுடன் கண்கள் தானாய் அலை பாயத் தொடங்கியது.. மெல்ல பைக்கின்    வேகமும் தணிந்தது .. சாலையை கடக்க  தயாராய் இருந்த ஒரு பெண்ணின் காலில் அபினவோட பல்சரின் முன் சக்கரம் ஏறியது.. அம்ம்ம்ம்மா என்ற சிறுஅலறலை தொடர்ந்து "பொறம்போக்கு பார்த்து போக மாட்டே" வார்த்தைகள் கடினமாய் இருந்தாலும் குரல் மிகவும் இனிமையாய்ஒலித்தது அபினவிற்கு..

"sorry  தெரியாம ஏறிடிச்சு" என்றவனின் வார்த்தையை காது கொடுத்து கேளாமல் தன் வழியே சென்றாள் அந்த பெண் விந்தி விந்தி.. வண்டியை stand போட்டு விட்டு அவளை நோக்கி சென்றான் அபி.. "ஏங்க sorry ங்க தெரியாம ஏறிடுச்சு.. நீங்க எங்க போனும்னுசொல்லுங்க நான் drop பண்ணிடறேன்" என்றவனுக்கு "ஆணியே புடுங்க வேணாம்" என்ற பதிலே கிடைத்தது..

அவளை பார்த்த மாத்திரத்திலேயே ஒரு இனம் புரியாத உணர்வு அபி மனதுள் பொங்கியது.. அவன் உள்ளுணர்வு அந்தப் பெண்ணைதொடரச் சொல்லியது.. அவன் வண்டி அவன் அனுமதியின்றி அதனை செய்ய தொடங்கியது..

ஸ்பென்சரில்  காத்திருந்த நண்பனுக்கு அபியின் பயணம் எத்திராஜுடன் திசை மாறியது தெரிந்திருக்க நியாமில்லை..

Wi-Fi (802.11abgn) - 2

Well. In last article we saw a simple introduction to wireless networks and simple connection protocol in a BSS.

Introduction to Wi-Fi

Let us march further little towards physical layer elements.

Channels:

Channels are nothing but the frequencies which are used to transmit the information over the air. As of now we got two spectrum for operation of Wi-Fi. One is 2.4 GHz Spectrum and other is 5 GHz Spectrum. The number of channels supported for a country is variable and guided by strict Regulatory domain.
Both the spectra are unlicensed spectra and can be used by non WLAN devices (Microwave oven, bluetooth for 2.4 GHz, Cordless phone and baby monitor for both 2.4 and 5 GHz) as well.

2.4 GHz Spectrum:

This spectrum starts from frequency 2.412 GHz. This 2.412 is the centre frequency for the channel 1. Every channel has bandwidth of 20 MHz out of that only 5 MHz is dedicated. The other bandwidth will be shared with neighboring channels. Hence every channel will have dedicated 5 MHz BW, 5 MHz BW shared by one neighboring channel, 5 MHz BW shared by two neighboring channel and 5 MHz BW shared by three neighboring channel.

In Asian Counties, Europe, the usage of channel 12 (2.467) and 13 (2.472) is also permitted. For 802.11b only operation channel 14 (2.477) is also allowed.
In 2.4 GHz spectrum, the standards 802.11b,g are specified specific to 2.4 GHz radio.

5 GHz Spectrum:

Unlike 2.4 GHz spectrum, 5 GHz spectrum has dedicated 20 MHz Bandwidth for every channel. The 5 GHz spectrum starts with channel 36 (5.18 GHz). We can split 5 GHz radio into three, viz. a. Lower 5 GHz (channels 36,40,44,48), b. Upper 5 GHz (channels 149, 153, 157, 161, 165), c. DFS channels (channels from 52 to 64 and 100 to 140).

There are strict regulatory domains which will guide the usage of DFS channel and 5 GHz spectrum for WLAN purpose. 802.11a standard is defined specific to 5 GHz radio.

40 MHz Bandwidth in 802.11n:

The default bandwidth for 802.11 is 20 MHz. But with developments in 802.11n standard the usage of additional bandwidth 40 MHz is also defined. In 40 MHz Channel Width Mode (CWM), the 20 MHz of the neighboring channel is also used. Under this case the neighboring channel will be termed as secondary channel or extension channel or data channel. The actual channel will be called as primary channel or control channel. The usage of 40 CWM is also referred as channel bonding.

In 2.4 GHz radio, for channel 1 the secondary channel will be 5 under extension channel spacing of 20 (default). Extension channel spacing should have a minimum value of 20 MHz.

For understanding more on extension channel let us assume the primary channel to be 1. Channel 1 shares its bandwidth with channel 2(15 MHz shared), 3(10 MHz shared) and 4(5 MHz shared) (Refer table for clean understanding).

If the Extension channel spacing is 15 MHz (less than 20 MHz), then the secondary channel for channel 1 will be channel 4

2.412(channel 1) + 0.015(extn channel spacing) = 2.427(channel 4)

Our frequency range will be from 2.402 (Starting of channel 1) to 2.437 (Ending of channel 4). Hence Bandwidth will be

2.437 - 2.402 = 0.035 GHz or 35 MHz.

In other words, Channel 4 already shares 5 MHz bandwidth with channel 1. Hence we will get only 35 MHz for our operation. As per standards two extension channel spacing is defined 20 MHz and 25 MHz. In 20 MHz ECS mode, extension channel will be primary channel (Plus or Minus) 4 and in 25 MHz ECS mode, extension channel will be primary channel (Plus or Minus) 5.

In case of 5 GHz, channel 36 will be bonded with channel 40 and vice versa. channel 44 and 48 will be bonded. 40 should not be bonded with 44 which will lead to violation of regulatory domain.

Recently, Wi-Fi organisation along with Wi-Gi is working on evolution of new standard which will operate on 60 GHz spectrum. Once the standard got defined, we may achieve a faster WLAN.

Wi-Fi (802.11abgn) - 1

Introduction:

Many will be using Wi-Fi products at home. Routers, Gateways, Stations, Mobile phones etc. Here I am going to share my knowledge on 802.11 WLAN technology. Whatever I have learnt in my 1 year experience, I will try to share with the world, in a simple lucid way.

Some useful links:

http://www.wi-fi.org/

http://www.wifinotes.com/

P.S. Here whatever I am going to share, they are purely based on ieee standards, my testing experience and learnings.

In Short:

To whomever, they are good in wired networks,

Literally there is no difference between wired and wireless networks on the top layer (OSI layers above Data Link Layer). The wireless networks differs only from the data link layer. In Wireless network, almost all the controls and managements are implemented in MAC sublayer. The MAC sublayer is fully responsible for establishing and maintaining the wireless connection. It is the only software layer which differs the wired and wireless networks.

802.11:

The wireless networks over small range is often referred as BSS (Basic Service Set). If you have a Wi-Fi Router or Access Point, to which one or more Laptops are connected, then they together form a Basic Service Set.

There are two types of BSS,

a. Independent BSS (IBSS), it lacks any master device such as Routers, Access Points(AP) or Gateways. It is a simple connection established between two or wireless stations (STA). The Ad-hoc network established between two or more laptops is best example for IBSS.

b. Infrastructure BSS (By default BSS refers to Infrastructure BSS), in infrastructure BSS there is an infrastructure element (e.g. AP, router) to which many STAs are connected and the infrastructure element is responsible for the connectivity and management of the WLAN (Wireless LAN).

For Initial articles, I will be dealing more with BSS than IBSS. Because it is easy to understand the protocols in BSS and later it will be so easy to map the same for IBSS.

BSS:

How Connection is Established:

As told earlier the BSS will have infrastructure elements, which will take care of the establishing and maintenance of the connectivity between different elements of the WLAN.

(i) Every infrastructure element should send beacons periodically to the air. "BEACON" is a Management Frame, which will tell clearly about the configurations of the wireless router such as SSID, channel, security mode etc.

(ii) STA will be sending as "Probe Request" which will have the STAs configuration.

The Beacons and Probe Requests are Broadcasted (Sent for everyone in the Air. The Destination MAC address will be FF:FF:FF:FF:FF:FF).

(iii) If a Network Infrastructure receives a matching Probe Req, i.e. the SSID, security mode and the other wireless parameters should be same, then it needs to response with a "Probe Response". From the Probe Response, the Packets will be unicasted (Sent to proper destination).

(iv) "Auth" Frames will be sent by the STA (will not be sent for OPEN Authentication).

(v) "Association Request" will be sent by the STA. In this stage, the STA would have get tuned to AP's parameters with reference to Probe Response.

(vi) "Association Response" will be sent by the Infrastructure Element to the STA.

(vii) The Key handshakes will take place for establishing the secure connection (This step will not be there for "No Security" connection).

All these connection frames can be analysed with wireless sniffer. Wireshark, Omnipeek, airmagnet are some of the widely used sniffer softwares. Your simple Wi-Fi capable laptop can act as sniffer with this softwares.

In the next article, we will learn about the wireless channels.

Veena - The queen of instruments

mangala vadhyam namastubyam|
sri brahmapathni hastha viharam||
adhi goraroopam naadhaadharam|
sakala chalachala vastu mohitam||

That implies: take my respects the spiritual instrument. You rest in the hands of saraswathi (brahma pathni). You are the most beautiful and you are base for the mighty music. You are successful in attracting all the stationary and dynamic (living and non living) things. These four lines are part of the song I am about to compose later.

I have said almost all I want to say in the above four lines. Though I wish to continue my article.

VEENA... a lovely instrument with melodious tones made wood and strings. Everybody would have seen veena atleast once in their life time... She is wonderful creation believed to be made by lord paramashiva himself.

There are several types of veena found in our history viz. Rudra veena, saraswathi veena etc. Veena is one of the greatest asset of indians. Let us restrict our focus to the most common veena of today i.e. saraswathy veena. It has 7 strings, 4 for main notes and 3 will be used similar to chords. The strings have names and they are

1. main strings :
a. sadjama string
b. panchama string
c. mandhara string
d. anumandhara string

2. sarani strings or chord strings:
a. aathara sadjama string
b. aathara panchama string
c. thara sadjama string

The main strings are used for playing the main notes whereas the sarani or chord strings will be played according to the period of tala or beat. For this reason veena is also called as sakala vadhyam.

Our Indian carnatic music has one more prestigious feature called GAMAKAS. Gamakas is quite a difficult topic to speak about and understand. So for now let me stop with the simple detail of this. Gamakas are classified into 10 types and veena is the only instrument which supports all the 10 gamakas.

Octaves and strings:

1. The sadjama string gives 24 different frequencies in the aathara stayi and thara stayi. The notes starts from aathara sadjama to shiva thara stayi sadjama. It corresponds to the normal octave and the octave above of the keyboard.
2. The panjama string gives the frequencies from madhira stayi panchama to thaara stayi panjama. It corresponds to the notes in the range between 'G' in the octave below the normal octave and 'G' in the octave above normal octave.
3. The mandhara string gives frequencies from mandhara sadjama to thaara sadjama and this corresponds to the octave lying below the normal octave and normal octave of the piano or keyboard.
4. anumandhara string gives frequencies from anumandhara panjamam to the sadharana panjamam. To speak in terms of octaves it starts one and half octave below the normal octave and lies till the 'G' of the normal octave.

Working:

Almost everyone will be aware of the relation between frequency and length, thickness etc. of the vibrating element. The frequency is inversly proportional to the length and thickness of the vibrating element. This is the basic principle of operation in the veena. The vainikar (veena player) will change the length of the vibrating element by pressing the string with his two fingers above mettu in order to produce notes with different frequencies.

The property of thickness of the string and different natural frequency of different elements is exploited to make the different strings to have different free natural frequency (the frequency achieved with full length).

To conclude, It is not easy to restrict the veena to a single article. It is just a start. We will be in constant touch.

Who rules whom

Well. This topic is very famous in the society. Confused?? You can very well come with an intelligent guess. Of course, I am going to talk about the endless and confusing conflict between the mind and heart. To be more accurate and to the point this post deals with the tug of war or a running war between the emotions and thoughts. Let us proceed...

Some people may be proud enough to say "I am rather a mind ruler". Congrats for them to be a mind ruler. But to what extent they are mind rulers? They may successful to say a no to one close friend; may be a winner in avoiding eyes to shed tears for things which induce the emotions; may be good in controlling their face to be index of heart. But are they successful in avoiding tears when someone close to them demises or atleast gets some pain?

The real mind ruler is one who under problems or stress thinks "What next" but not "How and Why this". If one starts thinking why/how this, he/she will be more interested in finding a blame which can be made on others and how to get themselves out of that problem successfully immaterial whether the problem gets solved or not. They wont give place to any emotions. So are they mind rulers??

Yes yes we cannot have a binary sets in psychology like digital electronics. The psycho sets are always fuzzy ones and overlapped indeed. But the majority wins not only in democracy but also in psychology. Even the great mind rulers failed to control their emotions in certain circumstances. So it is always filled with confusions.

How you want to be? Are you getting sick if someone begs for food; or someone tells you the most painful story? Does your eyes shed blood for sorrows which our earth bears? Welcome to the world of heart. You can enjoy sorrows pains everything. But you may be lacking in one thing. That is the easness of converting pains to pleasures.

The process of changing pains to pleasure is quite simple indeed. One small analogy. How big the sun is but how small it looks when we see from the earth! Thats what a real mind ruler does. He/she will stay far away from the problems and look for solutions. If one is near his problem he/she gives more weights to emotions rather than what they really feel. So the mind ruler knows how to make pains to pleasures.

Enough enough are you coming to say mind rulers are the best and the heart is not having any value. Never, seldom... Same analogy. If one sees the sun farthest, you obviously miss out to notice its real size. Similarly by evading the roots of emotions one miss out how big the issue is really.

So, which is best?

If one gives importance to thoughts than emotions, misses out how big the problem really is. If one gives importance to emotions to thoughts, no way the person has to live with the problem and he can hardly get solutions for that. So it is always better to be a mind ruler to arrive at a initial solution and later the solution can be developed by giving importance to emotions.

Now we are clear that by whom and how we want to get us ruled. The conflict between the mind and heart will exists forever. It is a battle running 24x7. Clearly define your stratergies for tough times. By that you can easily solve all the problems.

To be successful in life one needs to have a better control over his thoughts and emotions. It is one hard earned skill possessed by experienced persons. But if one really work on it, things can be made easy.

No goal is unreachable unless you dont want to reach it. Put yourself under stress. Think about the situations in multiple dimensions. Take decisions by thinking thrice or more [twice is surely not enough ;)] . Mistakes give you great lessons. One cannot have time to do all sorts of mistakes. So learn from others mistakes as well.

If one decides his ruler, then he is the ruler of the world. Mind and heart now goes together.

are you you?

how silly the question is! he is he; she is she; i am i; then why the hell question 'are you you?'? ok well. let me reframe the question by including myself and everyone in this beautiful land. are we we? think for a while by waking all your deepest past and embedded soul. you have enjoyed this world for -- years. in that long lived life how many of us got all our wants full-filled and live the life we really wanted?

suppose you would like to go for a pub but if your sweet girlfriend asks you to accompany her for shopping; also you would like to go to temple but your sweet heart wants you to come for beach; ranging from this small wishes to longer ones like you longed to become anthropologist or psychoanalyst but your parents made you a physician; then you wanted to marry mary but you end up with rosy;

how many unfruitful attempts, shattered dreams, unhappy situations! leave aside all those things. i agree we do not have control over wishes getting full-filled. but how many of us are allowed to take efforts to full-fill our wants, wishes or needs?

you are the part of society and since you want to live sticking to it, you loose all your independence and individuality. being a part in the society how many of us achieved the co-ordination between the greatest brain and so called mind? all are proud to say they are extroverts. do they really think they are extroverts? ok assume they are claiming for their extroversion. can they just imagine what are the things they had lost to earn the title of extroverts. the moment you are amicable with anyone your individuality is injured atleast for 1 per cent. now comes the conflict between mind and brain. brain is very practical whereas your mind is very sentimental. everybody's brain needs solitude in contradiction to this everybody's mind needs lovely relationships. so no one is completely extrovert nor completely introvert. we are just toys of situation and everyone is ambivert. assume their is a complete introvert and can we conclude that he/she can say YES for the topic. no he too cannot. because an introvert struggles hard to define his own YOU (by sticking to grammar HE/SHE) then how could he can say yes? the pitiable so called introverts are adjusting their personalities all the time for themselves.

we need love, affection and friendship. for that we need adjustments. obviously your individuality is lost whenever you are adjusting for someone immaterial whether the person for whom are adjusting is your mom, dad, spouse or any other relation. so you cannot be 100% you, but you can try to be a better you.

ya here goes some tips to make a better YOU.

# none other can play your role better than you. so stop comparing and changing yourself.
# live the day. forget the unpleasant past and do not bother for the unknown future.
# try to be independent to the maximum extent you can.
# find your matching spouse. if you can't what is the harm in leading a single life?
# always defend your deeds, actions and words.
# do not adjust for anybody unless it is absolutely necessary.

last words. if you go on caring about society you will be fooled everytime. people have no time to keep an eye on what you are doing. even if some shit does that what harm you are going to face with that. so, live for yourself. be a better YOU.

i am not against friendship or love. i am believing that being oneself is more important than friendship or love. keep your inner circle small or if possible even make it one with zero radii.

NOW ask yourself "are you you?"

Deekshidhar - A Great musician and Sanskrit Pandit

Everyone will be aware of the carnatic music trinities Muthuswamy Deekshidhar, Syama Sastrigal and Thiyaraja Swamigal. All of the three born in the divine place named Thiruvarur. Deekshidhar the youngest of the three lived in thiruvarur for his lifetime. All of his songs are in sanskrit and contains "Guruguha" as krithi karta mutrai (a mark of identification set by the composer). Many of his songs also have raaga mutrai (mark of identification for the raaga of song)also.

He had composed around 500 songs. He handled variety of raagas and talas for his krithis. His sanskrit knowledge will impress everyone. The depth of meaning found in the song will make us to fall to his feet. He had made songs on variety of deities right from lord shiva, loka janani matha shakthi, lord mahavishnu and his various avatars, lakshmi, ganapathy, murugan etc etc to lord ayyappan and vaatatmaja hanuman, whereas the other two focussed more on a single deity.

Though all his songs are beautiful and mind blowing, I like the following songs very much.

1. Amba neelayatakshi -- neelambari
2. Akilandeshwari rakshamam -- jujavanthi
3. Dharmasamvardhini -- madhyamavathi
4. Sri Varalakshmi -- sri
5. Hiranmayeem lakshmeem -- lalitha
6. Kanjathalayatakshi -- kamala manohari.

The list will be growing so I restrict myself with this six. I will be cursed by the musicians if I forgot to mention about the raaga Hamsadwani which is said to be discovered by the Deekshidhar's father Ramaswamy deekshidhar. Our music deity has composed one of the greatest song of hamsadwani on Lord Ganapathy "Vaathapi Ganapathim", which in my opinion an epitome for the raaga Hamsadwani.

Majority of his songs will have a madhyama kaala sahityam which will be in turita kaalam (sung with a faster phase compared to rest of the song), which will make the listener to amaze. He has composed 9 great songs on the goddess kamalambika of thiruvarur, the collection is called as Kamalamba navavarnam. All the songs will be spell bounding.

His sanskrit knowledge will be greatly exhibited in all of his compositions. I personally like the charana sahityam of kanjadalayadakshi and the pallavi of sri varalakshmi the most. He is the legend and no one can describe his knowledge and talent fully in words. This is a small attempt by an ordinary music lover.

To understand about the deekshidhar more one have to show his bakthi to the raaga, the god and the guruguha. Let us praise the god through various compositions of deekshidhar and lead a better meaningful life...

May Deekshidhar bless all of us and make us to prosper in life.

Love Makes Life Beautiful

Oh.. who don't want to love and be loved.. everyone does. it's such an attractive feel which is a god given gift for earthly creatures. right from the smallest grass to the so called six sensed human everybody loves and get love from others. when we are born, from mom, later from dad, at teens longing for a girls', from friends and lot lot of people. but have you ever tried to think why the love we get from one person is so different from some other person.??

many of us would not have. tat is the problem of we people. the parents love will be with us though we are not reciprocating any. but a friends love often needs a reciprocation, at least to a certain extent. but if it is to opposite sex (especially for guys who are trying to win a girls cute heart) it needs extreme efforts. you can at the maximum get some 20% of what you show. this is not the fault of those people. it is a fact which is quite natural.

winning a girls heart and make her to have a feel for you is a difficult task but if you achieved it you are one of the luckiest person. if a girl started believing you and accepts your love, she will give you the love which you cannot even dream. such a pure love is very hard to obtain.

guys here are a few tips to make you a better lover.

1. please be frank as much as you can.
2. no need to impress her with your look, but with your care and affection.
3. she expects nothing except a pure love affection and protection.
4. respect her wishes likes and dislikes

but make sure that the girl is not a sort of lots who will abuse your love and care. if you are fool enough to do that, many shrewd selfish girls are out to make you absurd.

girls think twice before you do things. it is a well known fact, in fact a proved one that the girl's mind is unstable and dynamic, but do not be dynamic in selecting your man. after all we guys expect only one thing from you which is nothing but a cute heart which is full of love.

i am blaming neither sex. she is so because she is a SHE and he is so because he is a HE. but everyone has common humanitarian characters which needs to respected and valued.

there are fellows who are just looking girls as a toy for sex. but i wont consider them as a human even. similarly there are girls who abuses a guy in the name of love. they are still worse. fellow men and women, try to show your human characteristics out, then you can observe how beautiful our blue planet is!!!

no one can be best man if he/she does not give respect to his/her fellow men. for the prats who involve themselves in brainwashing and canvassing what i can say is keep your dirty nose well away from the others' business. give respect to everyone's opinion. do not behave like a know it all.

love your parents, better-half, siblings, relations, friends, each and every fellow human beings and all living and non living creatures. life is short but make people to remember you by sharing your love.

LOVE MAKES LIFE BEAUTIFUL

To lead a better marital life

Though I am single, with my observations i am trying my best to say about some simple principles with which we can enjoy the happiest marital life.

First for guys,

The mistake often we people do is not showing our love explicitly to our spouse. Unfortunately that is the biggest expectation of the opposite sex. Many of the girls are complaining that their husband is not as same as he was before marriage. Guys think, we are spending more time waiting for girl friend when she was lover but failing to wait for even a 5-minute after marriage. Many of our people will go verbose on accusing girls for taking more time for dressing, make up and in shopping. But we people enjoy actually being out with beautifully dressed spouse. So what harm in waiting for she to get her things finished before going out? How much time we are spending in chat and surfing useless things? Think for a while.

Where do our romantic messages and talks vanishes after marriage? We people are comfortable with friends (of either sex) always, but not the same with our beloved spouse. Be romantic, flirt and joyful to the lady love forever. Just do that for a day and see the response it will be extremely pleasing.

Do not try lying with the wife. If you got caught red handed later the love meter readings will suddenly fall to negative values. Speak openly with the better half for at least some 15 minutes about the days' incidents before bed.

Try to fulfill her fantasies to the best possible extent. Do not forget to kiss before leaving for work. Take her out for a date at least once a week. If you follow these simple things you will be a deity for your lady.

My dear lady friends,

i. avoid calling, messaging or mailing your hubby unless it is absolutely necessary. Things such as "dear honey had lunch?" will be sweet for a few days but later it will be annoying when he found that message at peak of work

ii. Believe the fact that your man loves you the most than anything on this earth. But we poor guys are not talented enough to explicitly express it in innovative way everyday.

iii. Kindly treat generously your spouse's forgetfulness. If he forget something that is absolutely unintentional and it does not mean he has forgotten you and your love.

iv. Do not try to expose your possessiveness. Possessiveness is sweet but not always. Show it in times when it will be sounding beautiful.

v. Last but not the least do not compare yourself with your man's best friend (of either sex). You are so much important than the best friends for your hubby. So do not degrade your level by those silly comparisons.

With these things well understood you can make your man to do whatever you like. Also You can well root the thought that 'i am lucky to have her' in the brain for your guy.

For the betterment of both mr and mrs,

Understand the fact that 'giving away your own opinion for your spouse nature is a temporary solution. The permanent solution will be accepting his/her character'. Always give pleasant surprises to your better half (Make sure that it will be happy ones else surprises will become shocks). Share gifts on important days like anniversary, day of first meet, day of proposal etc. Greet at midnight 12 on the day of birthday with a sweet kiss and nice gift. Solve problems by having a nice conversation. Value the friends of your spouse. Better make them as your brother or sister.

You cannot lead a single life for long time. You may think you are happy as a single but reality differs. Let us make the earth a heaven and a very happy place to live in by leading a charming double family.

Long live anthropes.
