is the property of the atom and all substances in this universe has this. But in comparison to other metals this parispanda is exceedingly manifested in mercury. On account of this, it is amenable to changes at molecular, atomic and even tanmatrika levels. This quality in necessary for the creation of the type of energy required for both deha siddhi and lauha siddhi. Synonyms of mercury are rasa rasendra, suta, rasesvara, capala and rasa raja. All these are the synonyms of Lord Siva. Mercury in raw form is poisonous to body cells. The poisons of mercury are termed dosas. It has about 15 dosas. If all the dosas are not removed before administration, it will cause serious disease and even death. The dosas of mercury are removed b sodhana purification. The term particularly used for sodhana is samskara, caraka has explained this term as gunantaradhana. The first step in samskara makes the metal suitable for mardana (killing). In this process in mahabhautika composition of mercury reaches a state in which it is very close to mahabhautika composition of human body cells so that mercury will have a therapeutic effort. Then the physical and chemical impurities are removed, the next stop involves removal of toxicity. After this the attributes of the metal are transformed. The last step involves the regulation of physico-chemical attributes. In this process mercury will. The author experimented with the samskara of mercury fro January 1990 onwards and by the end of the year achieved some extent of success in rediscovering most of the procedures involved in this lost science, then he prepared a rasayana by combining the processed mercury with sulphur subsequently he tested the rasayana by self- administration on January , 1991. He took five grams of the rasayana every-day for a month. Photograph No 1 shows the author at his 58th year. Photograph No 2 shows the changes induced by the rasayana after 9 months of self- administration. The author, being a research oriented scientist, with an experience of 30 years in his field of specialization was not satisfied by the results obtained with one samskara, he repeated the process twice and made two batches of the rasayana, he self – administered a heavy dose from both the batches of rasayana in 1992 and 1993. The self-administration of heavy doses produced certain undesirable mental changes in the author, subsequently these were rectified with antidotes for removing from the body, elemental traces of mercury with dosa. Dehasiddhi of mercury began to manifest slowly on body mind and brain of the author from June 1994 onwards. Maximum benefit was for the brain. The changes which had taken place in his brain from January 1993 after self administer in second heavy dose in compared to “the churning of the ocean of Milk”, by the suras and devas, He feels and thinks that the is slowly moving towards a state of sthitaprajh without any kind of sadhana Only time will tell whether it is true or not. Self-administration of mercury purified by the author has show that (1) the three batches were identical and 2) all the three batches had some traces of dosas. Hence samskara of mercury in not 100% perfect. Experiments are in progress to induce complete dehasiddhi for mercury at the centre for advancement of Ayurveda and siddha systems of Medicine at Bangalore. Pages 264 - 267
