This volume explains the mysteries of Creation from the Vedic standpoint by an eminent scholar Pandit Motilal Shastri, a devout disciple of the much acclaimed Vedic guru, Pandit Madhusudan Ojha. It consists of five scholarly discourses presented before an august audience of well-known scholars and acaryas of Vedasastra, at Rashtrapati Bhawan during 14-18 December 1956. These discourses – Science of Agni-soma; the Science of Five Divisional Universe; Vedic Concept of Man: An Exposition; Science of Asvattha: An Outline; and Integrated Relationship of Vedasastra and Puranasastra – illuminate new insights into the mysteries of Creation, offering new definitions to well-known Vedic terms.
