Back to Absolute's content is derived from Vedic knowledge, which aims at perfection of self-realization. It is based on lectures, conversations and Vedic books written by A.C. Bhaktivedanta Swami Prabhupada. Since human life is the opportunity to get free from all material miseries, it is properly guided by the knowledge of the Vedas, in the matters of both material needs and spiritual salvation. The Vedas contain regulative principles of knowledge covering social, political, religious, economic, military, medicinal, chemical, physical and metaphysical subject matter and all that may be necessary to keep the body and soul together. The Vedic knowledge involves a gradual raising of the living entity to the spiritual platform, and the highest spiritual realization of knowledge about the Supreme Personality of Godhead.
