The Great Epic Mahabharatam :14.
A discourse of Swami Vivekananda on Mahabharata :
(Delivered at the Shakespeare Club, Pasadena, California, February 1, 1900)
So in those old days, they used to fight with magic arrows. One man would be able to fight millions of others. They had their military arrangements and tactics: there were the foot soldiers, termed the Pâda; then the cavalry, Turaga; and two other divisions which the moderns have lost and given up — there was the elephant corps — hundreds and hundreds of elephants, with men on their backs, formed into regiments and protected with huge sheets of iron mail; and these elephants would bear down upon a mass of the enemy — then, there were the chariots, of course (you have all seen pictures of those old chariots, they were used in every country). These were the four divisions of the army in those old days.
Now, both parties alike wished to secure the alliance of Krishna. But he declined to take an active part and fight in this war, but offered himself as charioteer to Arjuna, and as the friend and counsellor of the Pandavas while to Duryodhana he gave his army of mighty soldiers.
Then was fought on the vast plain of Kurukshetra the great battle in which Bhisma, Drona, Karna, and the brothers of Duryodhana with the kinsmen on both sides and thousands of other heroes fell. The war lasted eighteen days. Indeed, out of the eighteen Akshauhinis of soldiers very few men were left. The death of Duryodhana ended the war in favour of the Pandavas. It was followed by the lament of Gândhâri, the queen and the widowed women, and the funerals of the deceased warriors.
The greatest incident of the war was the marvellous and immortal poem of the Gitâ, the Song Celestial. It is the popular scripture of India and the loftiest of all teachings. It consists of a dialogue held by Arjuna with Krishna, just before the commencement of the fight on the battle-field of Kurukshetra. I would advise those of you who have not read that book to read it. If you only knew how much it has influenced your own country even! If you want to know the source of Emerson's inspiration, it is this book, the Gita. He went to see Carlyle, and Carlyle made him a present of the Gita; and that little book is responsible for the Concord Movement. All the broad movements in America, in one way or other, are indebted to the Concord party.
