Received: 29 June, 1995 Accepted: 10 August, 1995 ABSTRACT: The author experimented with the dehasiddhi using mercury. The interesting experiment is narrated in this article. The land of Bharath is the only place which developed the science dealing with the metal remedies for holistic health during the Vedic period when people in other parts of the world continued to use potions and witchcraft to cure diseases of the body. This science in Vedic language is termed rasa sastra. It uses metals such as iron, copper, silver, gold mercury, elements such as iron, copper, silver, gold mercury, elements such as sulphur, mica and other materials such as shells, pearls corals jewels, salts, etc in a purified and processed form for internal administration not only to cure diseases but also for the promotion of positive health. The dating of Vedic period is still a debatable subject. Some indologists believe that it began by the 13 century B.C However, it is accepted without controversy that 7 century B.C is a close approximation. Ayurveda is an Upaveda Rasa sastra is part of Ayurveda. Deva chikitsa, one of the four classified treatments recommended in AtharvaVada deals with the use of metals including mercury for positive health, caraka samhita composed by caraka prior to 7 century is the earliest work on rasa sastra similarly susruta samhita composed by susruta prior to 7 century B.C describes the use of metals for medicinal purpose, Rasa sastra flourished upto 4 century A.D., With a lull afterwards, Govinda bhagavatpada guru of Adi sanakaracharya gave a revival to Rasa sastra through his composition rasa hrdaya tantra during 9 century A.D It gave elaborate details for processing mercury for lauha siddhi (transmuting base metals into gold) and deha siddhi (making body free from aging process and disease leading to a state of jivan mukti). This science was treated as a secret science and a sacred one on account of the lauha siddhi of mercury. The gurus taught it only to disciples who would not misuse this sacred knowledge. The last guru who knew this science of inducing lauha siddhi and deha siddhi for mercury was late Pt. Sarma had his Samadhi in the 1940s. He did not teach this technique to anydody as he found all his disciples to be unworthy of receiving this sacred knowledge, Hence the knowledge of processing mercury for internal administration is lost even though the Government of India made many efforts afterwards to revive this science. Tamatras (quanta of energy) paramanus (atoms as conceived in Ayurveda) and Mahabhutas (Molecular entities as conceived in Ayurveda) are in a state of constant motion called parispanda, The term parispanda according to quantum mechanics Pages 264 - 267
