Brahma Sutras

The Brahma sūtras (Sanskrit: ब्रह्म सूत्र) is a Sanskrit text, attributed to Badarayana, estimated to have been completed in its surviving form some time between 450 BCE and 200 CE. The text systematizes and summarizes the philosophical and spiritual ideas in the Upanishads. It is one of the foundational texts of the Vedānta school of Hindu philosophy.

The Brahma sutras consists of 555 aphoristic verses (sutras) in four chapters. These verses are primarily about the nature of human existence and universe, and ideas about the metaphysical concept of Ultimate Reality called Brahman. The first chapter discusses the metaphysics of Absolute Reality, the second chapter reviews and addresses the objections raised by the ideas of competing orthodox schools of Hindu philosophies as well as heterodox schools such as Buddhism and Jainism, the third chapter discusses epistemology and path to gaining spiritually liberating knowledge, and the last chapter states why such a knowledge is an important human need.

The Brahmasutra is one of three most important texts in Vedanta along with the Principal Upanishads and the Bhagavad Gita. It has been influential to various schools of Indian philosophies, but interpreted differently by the monist Advaita Vedanta sub-school, the theistic Vishishtadvaita and Dvaita Vedanta sub-schools, as well as others. Several commentaries on the Brahma-sutras are lost to history or yet to be found; of the surviving ones, the most well studied commentaries on the Brahmasutra include the bhashya by Adi Shankara,Ramanuja, Madhvacharya, Bhaskara and many others.
