According to Wikipedia: "The Brahma sutras, also known as Vedanta Sutras, are one of the three canonical texts of the Vedanta school of Hindu philosophy. A thorough study of Vedanta requires a close examination of these three texts, known in Sanskrit as the Prasthanatrayi, or the three starting points. The Brahma sutras constitute the Nyaya prasthana, or "Logic-based starting point", of the above triplet. Thus they are also referred to as the Yukti prasthana, since Yukti also means reasoning or logic. 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."
