This is a reprint of the original 1999 edition with minor editorial changes. The Rigveda is the first book of humankind and the most sacred scripture of Hinduism. It also happens to be the most ill-understood book of our times. Despite the extensive study by academic and religious scholars, the purpose and meaning of the Rigveda and many ancient Hindu scriptures remain unclear. In this pathbreaking book, the discovery of the Rigveda as a book of ancient cosmology is described, and related to the seals of ancient Indus Valley Civilization, thereby challenging our perception of humanity. "The Vedas have always been lauded as containing the secrets of cosmogenesis. Raja Roy in his remarkable book shows how this is true not only from the yogic vison but according to the latest insights of modern physics. The book takes the reader on a vast panoramic journey through the universe of matter, mind and human history as well." David Frawley (Vamadeva Shastri) Director, American Institute of Vedic Studies "Roy presents a new framework for the understanding of the Vedic hymns from the point of view of physics and then he draws parallels with recent theories on the nature of the universe. We celebrate the new path he has hewn through the bush of old scholarship." Professor Subhash Kak Oklahoma State University
