The Upanishads form the basis of Vedanta. Vedanta is the basic culture of India. It is the national philosophy of India. It is the Moksha Sastra or the Science of Emancipation.
Absolutism is the pivot of Vedanta philosophy.
Vedanta upholds the reality of the indivisible, immanent and transcendent Spirit. It does not exclude matter. It does not exclude anything. The oneness of all existence is the message which Vedanta teaches. It has kept Hindu society alive for the past several thousand years.
