Brahma Sutra Bhasya
The Brahma Sutras, also known as Vedanta Sutras, constitute the Nyaya prasthna, the logical starting point of the Vedanta philosophy (Nyya = 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. The book gives word-to word meaning. --Wikipedia
