Dressing up like the Gods

Dressing up

Does dressing up really change the perception ? How often we have seen movies wherein the characters living in poverty themselves, just dress up nicely for an occasion and impress their affluence on others and take everyone a ride ! In 'Wedding crashers' Vince Vaughn/Owen Wilson play such characters with hilarious consequences.

Dressing up really seems to have benefits. People do notice that and form opinions based on that. Here is a beautiful verse from the "ocean" of Samskrita that emphasises that.

किं वाससा तत्र विचारणीयं वास: प्रधानं खलु योग्यताया: ।
पीताम्बरं वीक्ष्य ददौ स्वकन्यां चर्माम्बरं वीक्ष्य विषं समुद्र: ॥
Meaning:

The root vAs (10th gana) means to scent, to make fragrant.

What is there to enquire/discuss about pleasant appearances? Isn't making oneself pleasant only appropriate! The Ocean gave his daughter Lakshmi to Vishnu, but gave poison to Shiva.

This refers to the fact of churning the ocean by Devas and Asuras. The Ocean King (samudra:) had two extreme things with him to give away during churning - Lakshmi and halAhala poison.

He gave his daughter (svakanyAm dadau), ie Lakshmi to pItAmbara (dressed in yellow attire - Vishnu). Have you ever seen any pictures of Vishnu dressed up badly? And when the hAlahala visha had to be given, he gave it to charmAmbara (one dressed with deer skin)

Its a known fact that Shiva himself came to accept poison and Vishnu accepted Lakshmi. But the poet turns the story completely inside out and still manages to make sense of it. It appears now as if Ocean gave these two away and weaves the mentality of a father on how he would select his son-in-law.

What an imagination!

A Himalayan journey of a Raindrop

At this point of time, there are exactly 3 people whose very mention of the name gives me goosebumps. One of these is Kalidasa, the other two I will reserve for a later post.

The language is the vehicle of expression of human feelings. We often hear "I cannot express the feelings in words". Isnt it merely a limitation of the language? Suppose there is a language that would facilitate the expressions in a very precise and articulate manner. Would that be sufficient? Not necessarily. The human being who converses in that language must also be good enough to communicate it effectively.

Fortunately Panini 'established' a language called Samskrita which provides a medium to express pretty much everything a man could think of in terms of communication. But is that enough? Several playwrights, poets come along write great literature that enhances the language by their own small capacity. Several hundred years after Panini, comes Kalidasa and writes such a brilliant poetry which outshines all the other gems put together. Often Kalidasa is compared to Shakespeare. This is so wrong on several accounts. Kalidasa embellished what is only already a perfect language. Shakespeare had to deal with a less-than-so-perfect language like English and brings the beauty out of it. In that sense, Shakespeare's effort is like that of ant's ability to carry 700 times its own weight. (I am writing about Kalidasa, how can I not do similies!) But unlike Shakespeare, Kalidasa lived during the times of the giants of Samskrita literature, who unanimously recognized his greatness. Reminds of me a subhAshita: It is easy to find a great man, but it is hard to find a man who acknowledges the greatness of another man.

Here is a fantastic piece of poetry from kumArasambhava.

sthitA: kshaNam pakshmasu tADita adharA: payodhara utsedha nipAta chUrNitA: |
balIshu tasyA: skhalitA: prapedire chireNa nAbhim prathamoda bindava: ||

Lets rewrite this in prose order:

prathamoda bindava: kshaNam pakshmasu sthitA:
(ata:) tAditA: adharA:
(ata:) payodhara utsedha nipAta chUrNitA:
(ata:) tasyA: balIshu skhalitA:
(ata:) chireNa nAbhim prapedire |

prathama oda bindava: - The first drops of rainfall
kshaNam - for a while
pakshmasu - on eye-brows
sthitA: - rested (then)
tAditA: - lashed
adharA: - on the lips (then)
nipAta - fell
payodhara - on the breast
utsedha chUrNitA: - and pulverized into several droplets (then)
tasyA: - of her
balIshu - belly
skhalitA: - skidded down (then)
chireNa - after a long time
nAbhim - navel
prapedire - surrendered.

The description is about Parvati meditating in the Himalayas on Shiva to attain him as her husband.

See the verbs picked so appropriately for each action of the raindrop.

Rested on the eye-browse, lashed the lips, pulverized into droplets, skidded down the belly, surrendered to the navel.

Everytime I contemplate on this piece, it gives me goosebumps because of its unmatched precision in bringing out the beauty of the language. I just cant express my feelings in words :-)

Aryabhatta's pi value

The mathematical value pi has always been a curious number throughout history.

Here is Aryabhatta's version of the value of pi:


Lets split the words and understand the meaning:

चतुरधिकम् शतम् - Four more than hundred (=104)

अष्टगुणम् - multiplied by 8 (104 x 8 = 832)

द्वाषष्टि = 62

तथा सहस्राणाम् = of 1000 as such (=62000; totalling 62832)

अयुत द्वय = 10,000 x 2 (=20,000)

विष्कम्भस्य = of the diameter

आसन्न: - approximately

वृत्त परिणाह: - to the circumference.

In effect, 62832/20000 = 3.1416!

It interesting to note the large numbers he has used to arrive at Pi and the remark that pi is only an approximate value.

Aryabhatta's numerical encoding

The devanagari alphabets have been used in different fashions to denote mathematical numbers. A very popular such scheme is the katapayAdi sAnkhya notation, where a number is denoted by the formula

कादि नव टादि नव पादि पञ्चक याद्यष्टक ।
kAdi nava tAdi nava pAdi panchaka yAdyashtaka |

The katapayAdi scheme has been credited to vararuchi - वररुचि (author of chandra vAkya - चन्द्र वाक्य). Literature for this scheme is widely available on the net.

Another popular scheme is using commonly existing materials as representing numbers. For example, moon (चन्द्र / इन्दु) = 1; eyes (नेत्रे) = 2; rishi (ऋषि) = 7 etc. A more comprehensive list can be found here.

The katapayAdi scheme was probably not in vogue during the times of Aryabhatta. In his monumental work AryabhatIya, he introduces a very different scheme, specifically suited for representing astronomical numbers. His scheme was flexible while representing large numbers, which is especially true for astronomical calculations.

In his very innovative scheme, he successfully combines positional system with the devanAgarI-vowels and effortlessly represents large numbers upto 10^17.

Aryabhatta classifies the devanAgarI alphabets as varga (square) and avarga (non-square). This is purely his own classification based on positional system and has nothing to do with the alphabets itself.

Lets look at some definitions:

Defintion #1 - varga (square) consonants - वर्गीय व्यञ्ज्न

The vargIya consonants are represented like this:

1 2 3 4 5 6 7 8 9 10 11 12 13
क् ख् ग् घ् ङ् च् छ् ज झ ञ ट ठ ड
14 15 16 17 18 19 20 21 22 23 24 25
ढ ण त थ द ध न प फ ब भ म

Defintion #2 - avarga (non-square) consonants - अवार्गीय व्यञ्जन

The avargIya consonants are represented like this:

30 40 50 60 70 80 90 100
य र ल व श ष स ह

Definition #3 - Position of vowels

18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
औ औ ओ ओ ऐ ऐ ए ए लृ लृ ऋ ऋ उ उ इ इ अ अ
Definition #4 - Position of varga-s

Remember, 10th power := 10 ^ (#position - 1).

Varga positions are at squares of 10, namely 1, 100, 10000 etc (#position = 1,3,5 etc)
Avarga positions are at non-squares of 10, namely 10,1000 etc (#position = 2,4,6 etc)

The usage of vowels for positioning/notational system is a very striking feature of this scheme. The simplicity of denoting large numbers will become evident as we explain the scheme.

With such a system in place, the following can be established:

  • Numbers take their positional life when a consonant is combined with the vowel.
  • The avargIya consonants can go only into positions of 2,4,6 etc.
  • The vargIya letters can go only into positions of 1,3,5 etc.
  • The length of vowel does not influence the number (ka क and kA का) are one and the same.

Finally, remember that in Samskrita math tradition, the numbers are read from right to left. This is by the rule अङ्काणाम् वामतो गति:। (Numbers go from right)

Before we jump into deciphering numbers, lets recap on what letters should go where.

18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
यौ यो यै ये य्ल्रृ यृ यु यि य
30 30 30 30 30 30 30 30 30


Now lets look at some real world examples:

Simple examples
Well, 100 is pretty much pre-defined (ha - ह)

Eg: khi (खि)

kh = 2, varga, i (इ) denotes position 3 = 10^2, so khi = 200

Eg: ju (जु)

j = 8, varga, u (उ) denotes position 5 = 10^4, so ju = 80,000

Eg: yRu (यृ)

y = 30, a-varga, Ru (ऋ) denotes position 8 for avarga = 10^7, so yRu = 30x10^7 = 3x10^8.

So a simple यृ denotes 3x10^8! (think of speed of light in km/s in a vaccuum).

Some more larger numbers:

nu (नु) = 20 x 10^5 = 2,000,000 (2 million)
mau (मौ) = 25 x 10^17! (2.5 billion billion)

Lets look at other numbers:

Eg:
Number Number in reverse Scheme
125 = 25+100 ma-ha
225 = 25+200 ma-khi (2*10^2)
5335 = 5+30+300+5000 = ङयगि
432,000 = 2000 + 30000 + 400000 = ख्युघृ

Aryabhatta gives several such numerals based on this scheme including number of rotational years of planets and moon, sine tables etc.

But his scheme did not gain popularity. One reason could be the difficulty in pronouncing the words as a result of such an encoding. Another reason could be the katapayAdi scheme, which could blend beautifully with the poetry.

Comparison of katapayAdi and Aryabhatta's scheme:

An easy difference between katapayAdi and the Aryabhatta's scheme is, whereas the former uses 1:M mapping of numbers:letters (one number can be represented by several letters; for eg 1 can be represented by ka-,ta- or pa-), Aryabhatta's is pretty much a 1:1 mapping. The flexibility of the former yields itself to great poetry.

In katapayAdi scheme, vowels do not carry any significance (all vowels are either ignored or equated to 0). Also the half-consonants are ignored. But in Aryabhatta's scheme, vowels play a major part, in fact it "powers" the numbers.

Who is equal to Kalidasa?

That mahAkavi kalidAsa is one of the greatest poets is perhaps already a cliche. From Bhavabhuti to Goether several personalities have paid very rich tributes to him. In the history of world literature, from time to time one finds a gem that lauds him to the sky. Here is one such a beauty.


पुरा कवीनां गणनाप्रसङ्गे कनिष्ठिका अधिष्ठित कालिदासा ।


"Long ago when poets met together, they agreed that KAlidAsa is equal to the pinky finger."

Very insulting indeed! How could one equate Kalidasa the greatest of poets to a pinky finger?! Isnt it preposterous? Has this guy even read any of Kalidasa's works?


Well here comes the unassuming punch line as the next part of the subhAshita:


अद्यापि तत्तुल्य कवे: अभावात् अनामिका सा अर्थवती बभूव ॥

"Even today due to the absence of a poet of equal stature, the next finger remains meaningfully to be called as "anAmikA" (Unnamed)."

(In Samskrita, the ring finger is called "anAmikA".)

What a master stroke!

A spatial palindrome sloka

It is often not hard to imagine in a seemingly infinite compendium of Sanskrit Literature, there are some gems just lying hidden only to be discovered.


Such gems may be simple yet attractive alliterations, double/triple or even quadruple meanings for each word, split-word meanings or the most amazing - containing some mathematical pattern.


My dad recently gifted me the सुमध्व विजय महा काव्य (Sumadhva vijaya or The Successful Travel of Sri Madhvacharya) book by a great scholar named श्री नारायन पण्डित (Sri Narayana PaNdita). This book must have been written around 13th century CE. This book has about 1008 slokas, but the same content has been briefed to 32 slokas by the author himself. I thought it must be a routine Sanskrit text, with plenty of slokas in it. But to my surprise, among several others, I found one gem of a sloka which just shines like a brilliant diamond. See for yourself.

समानया यानमास मायया ततयायमा ।

नयासना नासयान यातनाललनातया ॥

Interpreting a Samskrita verse can be a daunting task. The main reason being Samskrita sentences, broadly speaking, do not have implicit order. This characteristic is very typical of inflexional languages. Add to that a poetic license that could let one place in any place they want to fit the metres (chandas).


However for understanding the sloka, there are a few simple rules. The first and foremost is called the पदच्छेद (padaccheda, lit. cutting of words). The next is to find the verb and then the associated subject. When a verb is not present, an "is"/"exists" is assumed implicitly. Then one should find the accusative object(s). Third is to find the qualifying attributes of the object. These are adjectives. Finally, one could dissect the rest of the cases and make a meaningful sentence.

Lets start with the word splitting.

समानया या अनमा आस मायया ततया अयमा ।
नयासना न आस या न यातना अललना अतया ॥


And here is the word by word meaning:


या That philosophy (of Sri Madhvacharya) which
समानया is established with the true propositions (yukti)

ततया vyAptamana
मायया by the illusion (mAyA)

अनमा आस cannot be refuted.
अयमा This incomparable philosophy

नयास is true by itself
न आस न and is not unexisting (that is, it is true for sure)

अतया By the opposing philosophies
अललना unhappiness (misery)

यातना the tamas causing
(भवति) happens


Whew! I say. I need his help for my GRE to pass the logical tests. Ok, lets not go into the actual philosophy perse. We understand in general that Sri Madhvacharya's philosophy is superior to Maya theory. Lets not go further for now, but just appreciate its beauty. At first glance, it pretty much looks there is some poetry going on. A few repeated syllables could be a good indication of some alliteration. But there is more to it.

The first thing to notice is that in each quarter, the second word is the syllabic-reverse of the first word. That is,

samAnayA := syllabic_reverse(yAnamAsa).

Same applies to other quarters. Which means, each quarter is a palindrome. "samAnayA yAnamAsa" is a palindrome by itself.


No big deal, you say. There are thousands of Sanskrit examples like this! Good, I'm glad there are :-).

Now let me write each quarter of the verse in a row, and then repeat the same in reverse order.


स मा न या या न मा स
मा य या त त या य मा
न या स ना ना स या न
या त ना ल ल ना त या
या त ना ल ल ना त या
न या स ना ना स या न
मा य या त त या य मा
स मा न या या न मा स

Now read the verse, in the following order:

  1. Start from top-left, horizontally, going left to right. (then move to next row)
  2. Start from top-left, vertically, going top to bottom (then move to next column).
  3. Start from top-right, horizontally, going from right to left.
  4. Start from top-right, vertically, going from top to bottom.
  5. Start from bottom-left, horizontally, going from left to right (then move to previous
  6. row)
  7. Start from bottom-left, vertically, going from bottom to up (then move to previous
  8. column)
  9. Start from bottom-left, horizontally, going from right to left.
  10. Start from bottom-left, vertically, going from bottom to top.

You should be seeing the pattern now. It reads same in every direction!

Now what do we call such a 'palindrome' ? A symmetric spatial palindrome is probably an apt description!

Well the real question is "what else is out there?"
