Traditional Badarayana (IAST Bādarāyaṇa; Devanāgari बादरायण) was an Indian philosopher and sage who was the reputed author of the Brahma Sutras.
The Brahma Sutras is a source text for the Hindu philosophical school of Vedānta and one of three texts along with the Upanishads and Bhagavad Gita which establish the prasthantrayi.
[1][2][3][4] His work Brahma Sutras is variously dated from 500 BCE to 450 CE.
[7] Bādarāyana is regarded as having written the basic text of the Vedanta system, the Vedāntasūtra a.k.a.
[8] He is thus considered the founder of the Vedānta[9] system of philosophy.
