The Brahma Sūtras, also called the Vedānta Sūtras, are some 555 aphorisms that systematize the teaching of the Upaniṣads on Brahman. They are so brief that they can hardly be read without a commentary, and each school of Vedānta established itself by writing one: Śaṅkara’s, Rāmānuja’s and Madhva’s are the best known. Tradition attributes the work to Bādarāyaṇa, sometimes identified with Vyāsa.
