Brahma Sūtra

Written by the rishi Badarayana, the Brahma Sutras are the earliest extant systematic exposition and reconciliation of the philosophy of the Upanishads. The Brahma Sutras are also known as the Vedanta Sutras and śārīraka Sutras.

Sri Ramanuja’s principal commentary on the Brahma Sutras is known as Sribhashya. He has also written shorter commentaries for the benefit of easy comprehension. The Vedānta Sāra is a very brief work, explaining merely the meaning of the words of each sutra and their connecting ideas, and was written before the Sribhashya. The Vedanta Dīpa was written after the Sribhashya and is of medium length.
