Nagarjuna was born at Fort Daihak near the famous shrine of Somnath in Gujarat in 931 A.D. He was a chemist, or an alchemist, as his efforts had been concentrated on transforming the base metals into gold. He had acquired such a reputation, due to his activities, that the people believed that Nagarjuna was in communion with gods and goddesses who had blessed him with the power of changing base metals into gold and the extracting of 'elixir of life'.
Nagarjuna himself believed in the idea of his being looked upon as blessed by the gods. He added to this belief by writing his treatise, Rasaratnakara in the form of a dialogue between him and the gods. The treatise dealt with the preparation of rasa (liquids, mainly mercury). Nagarjuna has discussed various combinations of liquids in this volume. His treatise, the Rasaratnakara also gave a survey of the status of metallurgy and alchemy as it existed in India in those days.
Methods for the extraction of metals like gold, silver, tin and copper from their ores and their purification were also mentioned, in Rasaratnakara. In his attempt to prepare the 'elixir of life' from mercury, Nagarjuna made use of animal and vegetable products, apart from minerals and alkalis. For the dissolution of diamonds, metals and pearls, he suggested the use of vegetable acids like sour gruel and juices of fruits and bark.
In his treatise, he has also listed the apparatus that was used by earlier alchemists. The process of distillation, liquefaction, sublimation and roasting were also mentioned. Nagarjuna also discussed, in detail, the possibility of transmutation of base metals into gold. But although he could not produce gold, these techniques did yield metals with gold like yellowish brilliance. Till today these methods are being used to manufacture imitation jewelry.
Nagarjuna has also discussed methods for the preparation of mercury like calamine. Later Nagarjuna seems to have turned towards organic chemistry and medicine. He has written a text called Uttaratantra which is supposed to be a supplement to an earlier text the Shusruta Samahita which is written by Shusruta in the 8th century B.C.
Nagarjuna's Uttaratantra deals mainly with the preparation of medicinal drugs. He also wrote four Ayurvedic treatises named Arogyamanjari Kakshaputatantra, Yogasara and Yogasatak.
Thus Nagarjuna seems to have been a copious writer. As he lived in the 10th century his works incorporate the ideas of earlier chemists and physicians. Only a few decades after Nagarjuna, India was invaded by the Mohammedans: Mahmud of Ghazni had raided and plundered Nagarjuna's hometown of Somnath in 1020 A.D. It is possible that Nagarjuna's texts fell into the hands of the invaders.
While the invaders ruthlessly destroyed the architectural achievements of this country and imposed their despotic rule, they also transmitted Indian sciences to the outside world.
Along with Mahmud of Ghazni came scholars like Al Beruni who studied Indian texts and translated them into Arabic. Many Indian ideas of medicine were incorporated into the Unani system of medicine of the Arabs. Nagarjuna's works could not have escaped their attention. It is possible that the technique of alchemy was borrowed by the Arabs from India. In the ancient world there is no reference to alchemy. We first hear of it in the medieval Europe. The homeland of the Arabs is not rich in metals, thus alchemy and the smelting of metals could not have been indigenous to the Arabs.
Thus the Arabs seem to have borrowed the technique of transforming base metals info gold-like metals from India. The Arabs called the technique Al Kimia which according to the Oxford Dictionary literally means the 'transformation of metals'. Al means 'The' and Khimia which is derived from the Greek term Khemia means 'to transmute metals'.
But westerners did not appear to have had the knowledge of the technique of alchemy. This is borne out by the fact that the term Alchemy which the westerners use for describing this technique was borrowed from the Arabs. The word Alchemy is obviously a corruption of the term Al Kimia which the Arabs gave to the technique of converting base metals into gold like substances which they culled out from Indian texts on the subject.
I wish the people of India would realize, that the texts from ancient India are much much more valuable than their weight in gold !
