"The Brahma sutras, also known as Vedanta Sutras, constitute the Nyaya prasthana, the logical starting point of the Vedanta philosophy (Nyaya = logic/order). No study of Vedanta is considered complete without a close examination of the Prasthana Traya (Prasthanatrayi), the texts that stand as the three starting points. The Brahma Sutras are attributed to Badarayana. While the Upanishads (Sruti prasthana, the starting point of revelation) and the Bhagavad-Gita (Smriti prasthana, the starting point of remembered tradition) are the basic source texts of Vedanta, it is in the Brahma sutras that the teachings of Vedanta are set forth in a systematic and logical order. While the earlier commentators like Adi Shankara treat Badarayana, the author of the Brahma Sutra, as the Jnana-Shakti Avatara (knowledge-power incarnation) of God, Vaishnavite tradition identifies him with Krishna Dwipayana Vyasa, the author of the Mahabharata."
