The text attributed to Badarayana designated Brahma-Sutra or Sariraka-Sutra occupies the foremost position of authority in the system of Vedanta. That there were commentaries on it even before Sri Sankara we learn explicitly from Sri Sankara himself, whose commentary is the earliest available now. Its central status in Vedanta is thus very well established. This is understandable as it explicitly endeavours to formulate, elaborate, and defend the philosophy of the Upanisads in the full-fledged darsana style. The Bhagavad Gita seems to accord to it this pivotal status in the one significant reference we have in it.

Mangalacharana bhramika adhyaya ke avataranika, Laghu purvapaksha.
