Arjuna’s Arrows & Algebra🧵

Bhāskarāchārya (1114 -1185 CE),has been called the greatest mathematician of medieval India.
He's considered the progenitor of Differential Calculus-500 years before Newton and Leibniz

Bhāskarāchārya wrote at least four mathematical

treatises in Sanskrit.
One of them,titled Leelavati,contains many algebra-related teasers,which have become the subject of significant research by scholars.

These teasers are in the form of shlokas which pose the problems.
The shlokas need to be interpreted

correctly to decipher the meaning in order to find the solution.

पार्थ: कर्णवधाय मार्गणगणं क्रुद्धो रणे संदधे तस्यार्धेन निवार्य तच्छरगणं मूलैश्चतुभिर्हयान् |
शल्यं षड्भिरथेषुभिस्त्रिभिरपि च्छत्रं ध्वजं कार्मुकम्  चिच्छेदास्य शिरः शरेण कति ते यानर्जुनः संदधे  ७६

Take a look at this shloka above. The direct meaning of this shloka is a question formulated as follows

During the battle between Arjuna & Karna in the Mahabharata, Arjuna released some arrows.Of the released arrows:Half were consumed in stopping the arrows coming from Karna
⤵️

4 times the squareroot of the arrows were consumed to control the horses of Karna's chariot,6 were for gaining control over Shalya,the charioteer of Karna. (Shalya was the maternal uncle of Nakula and Sahadeva),3 were used to take on the umbrella & flag off

the chariot and the bow of Karna.
Finally Karna was killed by a single arrow. So how many arrows were released by Arjuna in the battle ?

Basic algebra easily yields the answer to this question, if the equation is formulated correctly.

Let the total number of arrows be X.

⤵️

The statements above can be reduced to the algebraic form

X = X/2 + 4√X + 6 + 3 + 1

Solving the above, we get the value of X=100 for the total number of arrows shot by Arjuna.

However, the fun is not just in getting the algebra right. There is so much hidden information

⤵️

in this shloka. If we pause to think a little deeper about the hidden meanings :

Even for an atirathi like Arjuna, it took as many as 50 arrows to stop the arrows of Karna - it tells us about the skills of Karna.

That the horses needed 40 arrows to immobilize the chariot

⤵️

tells us about the kind of training given to the horses in the battle field.When even the horses needed 40 arrows,that Shalya the charioteer surrendered with just 6 tells us that he is favouring Arjuna.
3 arrows to take the chariot and the bow shows the helplessness of Karna.

⤵️

Once everything is in control the enemy should vanquished in just a single arrow.

So the rules and skills required to win such a battle operationally are :

Firstly,stop the enemy fire-power

Second, immobilize the enemy by taking on his mobility- the horses and the driver

⤵️

Thirdly signal to him his helplessness by destroying the carriage, and finally eliminate the enemy himself.

If we analyze the same shloka on the spiritual side :

To attain ultimate liberation,firstly one needs to control over his/her personal desires,this being a difficult

⤵️

task,thus takes 50 arrows.

Then take control over 5 senses and sensual pleasures indicated by the horses.The 40 arrows needed to do this indicate the difficulty of the task.

Gaining control over 5 senses will lead one to the control over the consciousness (manas,thought,ego)
⤵️

indicated by the driver.If all the foregoing are done, achieving the ultimate liberation (moksha) should be relatively easy.

This is the greatness of our ancestors & #SanatanaDharma - #Vidya integrated with #values

A single shloka includes so much of knowledge!
