According to Multhauf & Gilbert (2008):[91]
The oldest Indian writings, the Vedas (Hindu sacred scriptures), contain the same hints of alchemy that are found in evidence from ancient China, namely vague references to a connection between gold and long life. Mercury, which was so vital to alchemy everywhere, is first mentioned in the 4th- to 3rd-century-BC Artha-śāstra, about the same time it is encountered in China and in the West. Evidence of the idea of transmuting base metals to gold appears in 2nd- to 5th-century-AD Buddhist texts, about the same time as in the West. Since Alexander the Great had invaded Ancient India in 325 BC, leaving a Greek state (Gandhāra) that long endured, the possibility exists that the Indians acquired the idea from the Greeks, but it could have been the other way around.
Significant progress in alchemy was made in ancient India. Will Durant wrote in Our Oriental Heritage:
"Something has been said about the chemical excellence of cast iron in ancient India, and about the high industrial development of the Gupta times, when India was looked to, even by Imperial Rome, as the most skilled of the nations in such chemical industries as dyeing, tanning, soap-making, glass and cement... By the sixth century the Hindus were far ahead of Europe in industrial chemistry; they were masters of calcinations, distillation, sublimation, steaming, fixation, the production of light without heat, the mixing of anesthetic and soporific powders, and the preparation of metallicsalts, compounds and alloys. The tempering of steel was brought in ancient India to a perfection unknown in Europe till our own times; King Porus is said to have selected, as a specially valuable gift from Alexander, not gold or silver, but thirty pounds of steel. The Moslems took much of this Hindu chemical science and industry to the Near East and Europe; the secret of manufacturing "Damascus" blades, for example, was taken by the Arabs from the Persians, and by the Persians from India."
An 11th century Persian chemist and physician named Abū Rayhān Bīrūnī reported that they "have a science similar to alchemy which is quite peculiar to them, which in Sanskrit is called Rasayāna and in Persian Rasavātam. It means the art of obtaining/manipulating Rasa: nectar, mercury, and juice. This art was restricted to certain operations, metals, drugs, compounds, and medicines, many of which have mercury as their core element. Its principles restored the health of those who were ill beyond hope and gave back youth to fading old age." One thing is sure though, Indian alchemy like every other Indian science is focused on finding Moksha: perfection, immortality, liberation. As such it focuses its efforts on transmutation of the human body: from mortal to immortal. Many are the traditional stories of alchemists still alive since time immemorial due to the effects of their experiments.
Since alchemy eventually became ingrained in the vast field of Indian erudition, influences from other metaphysical and philosophical doctrines such as Samkhya, Yoga, Vaisheshika and Ayurveda were inevitable. Nonetheless, most of the Rasayāna texts track their origins back to Kaula tantric schools associated to the teachings of the personality of Matsyendranath.
Two famous early Indian alchemical authors were Nāgārjuna Siddha and Nityanātha Siddha. Nāgārjuna Siddha was a Buddhist or Jaina monk. His book, Rasendramangalam, is an example of Indian alchemy and medicine. Nityanātha Siddha wrote Rasaratnākara, also a highly influential work. In Sanskrit, "rasa" translates as "mercury" and Nāgārjuna Siddha was said to have developed a method or converting mercury into gold.[92]
Reliable scholarship on Indian alchemy has been advanced in a major way by the publication of The Alchemical Body by David Gordon White.[93] Trustworthy scholarship on Indian alchemy must now take the findings of this work into account.
An important modern bibliography on Indian alchemical studies has also been provided by David Gordon White at Oxford Bibliographies Online.[94]
