The fundamental idea of all Indian philosophy is one common to the highest human thinking everywhere. The supreme truth of all that is a being or an existence beyond the mental and physical appearances we contact here. Beyond mind, life, and body there is a spirit and self containing all that is finite and infinite, surpassing all that is relative, a supreme absolute originating and supporting all that is transient, a one eternal. A one transcendent, universal, original, and sempiternal divinity or divine essence, consciousness, force, and bliss is the fount and continent and inhabitant of things. Soul, nature, life are only a manifestation or partial phenomenon of this self-aware eternity and this conscious eternal. But this truth of being was not seized by the Indian mind only as a philosophical speculation, a theological dogma, an abstraction contemplated by the intelligence. This chapter indicates the central characteristics of Indian culture as it has grown from its beginning to its present positions.
