The Anu Gita

In the Ashvamedhika Parva of the Mahabharata, after the war, Shri Krishna teaches again when Arjuna asks him to repeat the wisdom of the Gita.

After the Kurukshetra war had ended and Yudhishthira had been crowned, Shri Krishna and Arjuna were one day sitting together in the beautiful assembly hall at Indraprastha. Arjuna humbly said that, because of the restlessness of his mind, he could no longer properly remember the knowledge the Lord had given him before the battle, and asked him to tell it again. This episode comes in the Ashvamedhika Parva of the Mahabharata, and the teaching is called the Anu Gita, meaning "the Gita that follows".

Krishna expressed some regret that Arjuna had not held on to that knowledge. He also said that at that time he had been absorbed in yoga, and could not now repeat it in exactly the same words. Even so, out of affection for Arjuna, he explained the same essence again through ancient stories.

The Anu Gita includes a dialogue between a perfected sage and the rishi Kashyapa, a dialogue between a brahmana and his wife, and a dialogue between a teacher and his disciple. Through these it explains the nature of the self, the cycle of birth and death, the results of action, control of the mind and senses, the three gunas and the means to liberation.

The Anu Gita is not as well known as the Bhagavad Gita, but scholars regard it as a companion to the Gita's teaching. It also carries a gentle lesson of its own: hearing spiritual knowledge once is not enough; it must be remembered again and again and practised until it becomes part of one's life.
