The three basic text of the Vedanta school of thought is referred to as Prasthana – Traya. They are Upanishads Bhagavad Gita and Brahmasutra Brahmasutra of Badarayana is a treatise on the nature of Ultimate Reality and Truth (Brahman) as propounded by the Upanishads. Brahmasutra is also known as Vedanta Sutra and Sariraka Sutra. Bhagavad Gita forms part of the Bhishma Parva of the Mahabharata. It is in the form of a dialogue between Arjuna and Sri Krishna. Today, Bhagavad Gita is like the Bible of Hindus. It also contains the teachings found in the Vedas. The vast knowledge of Vedas is condensed in eighteen chapters. Upanishads are part of the Vedas and they are the basis of all philosophical teachings in Hinduism. The great Rishis who searched for answers to disturbing questions like who am I, Where did I come from? , Where will I Go? Is there a return?... etc poured out their thoughts in the Upanishads.

Bhagavad Gita is the essence of the Vedas. It contains all the scriptural teaching in Hinduism. A great saint said All the Upanishads are the cows, the Lord Himself is the milker, Arjuna, the calf and those of purified understanding are the drinkers of the milk, the supreme nectar of the Gita. For the soul there is neither birth nor death at any time. The soul is unborn, eternal, ever-existing and primeval. The soul is not slain when the body is slain. The soul can never be cut to pieces by any weapon, nor burned by fire, nor moistened by water, nor withered by the wind. You have a right to perform your prescribed duty, but you are not entitled to the fruits of the action. Never consider yourself to be the cause of the results of your activities, and never be attached to not doing your duty.
