Garbha Upanishad

It is associated with the Krishna Yajurveda by some, and as a Vedantic Upanishad associated with the Atharvaveda by other scholars. It is considered as one of the 35 Samanya (general) Upanishads. The Garbha Upanishad is a text that almost exclusively speculates on medical and physiology-related themes, dealing with the theory of the formation and development of the human embryo and human body after birth. The Upanishad gives details of the elements (essential parts and principles) and various features of the body and gives detailed explanation on the evolution of the embryo in the mother’s womb. The text is notable for its style, where it states a proposition, asks questions challenging the proposition, thereafter develops and presents answers to those questions. It is also notable for its attempt to enumerate and offer relative measure of human anatomy from foetus to adult stage of human life.
