This book deals with the scientific and philosophical analysis of certain aspects of life in relation to the reality in its absolute form which is equated with consciousness. There is a search after the reality in different forms such as physical, biological and philosophical and spiritual. In discussion are such branches of knowledge as evolutionary biology, neuroscience, quantum physics and Western and Indian (Vedic) philosophy. Attempts are made to understand the meaning of "real and unreal" in the context of life and consciousness.
