The Vedanta philosophy is important both for its philosophical views and its close connections with the existing Hinduism. Uttara Mimamsa (also called Vedanta Sutra or Brahma Sutra) of Badarayana deals with the Brahman doctrine. It consists of 555 sutras. Vedanta bases its many observations and explanations on Samkhya system. Vedantist does not accept multiple Purushas; Reality is one as Brahman and the rest of the universe including mind and its modifications are but superimposition upon this one Reality.The word Vedanta is a compound of veda "knowledge" and anta "end, conclusion", translating to "the culmination of the Vedas".
