Human physiology is an express of Vedic Sound—Veda and the Vedic Literature are the essential constituents of the structures and functions of human physiology. In Dr. Tony Nader's book, Human Physiology: Expression of Veda and the Vedic Literature, he examined human physiology in great detail, and demonstrated the one-to-one relationship between the different parts of the physiology and the different aspects of the Vedic Literature. The structure of each branch of Vedic Literature corresponds perfectly with the structure of a specific aspect of the physiology.
Selected graphics from that book (particularly relevant for our course 'Advanced Vedic Science'), illustrating the correspondence between specific branches of Vedic Literature and specific aspects of the physiology, can be viewed by clicking on the links below in our chart of the 40 branches of Veda and the Vedic Literature.
