Rasaprakāśasudhākara

Now the transiting work of mercury is described. (140)
Without the shell-acid a powerful solvent made from conch shells, one cannot transit the mercury properly. Buffalo ear-wax, woman's milk, mixed with borax— (141)
Taking these equal materials, grind them for a day. Poison, cinnabar, Rasaka, and red-kanta a type of mineral— (142)
Lady-bug, Tumvari, pyrite, and crow-feces. (143)
With this paste, place the mercury in the middle. (144)
Adding glass powder, heat it in a blind-crucible. By this transiting, the mercury moves in an instant. (145)
This transiting is excellent, experienced by Nandi-Raja. Pyrite-essence and lead, purified, are always for transiting. (146)
Seeds and mercury transit; there is no doubt.

Now I shall speak of the transmutation method in detail. (147)

By knowing this, a man becomes a knower of transmutation. Dhurta oil, snake-foam, Kankuṇī oil— (148)
Horn-oil, poison, and oil derived from nutmeg. (149)
Horse-killer Hayamāra Nerium oleander oil, and Viṣoṣaka oil. (150)
Know these and other oils to be transmutation-makers. Rubbed with these, the accomplished mercury becomes a transmuter. (151)
Smear-transmutation, throw-transmutation, lance-transmutation, smoke-transmutation, and sound-transmutation are the five types of transmutation. (152)
Take thin copper plates, made of silver-like substances, smeared with paste, and heat them in a blind-crucible. (153)
When cooled, lift it out; this is called smear-transmutation. When copper or silver is molten, throw the mercury into it. (154)
It is transmuted instantly; this is called throw-transmutation. Melt copper and silver, and others. (155)
Apply the molten mercury into one of the vessels. It is transmuted; it is lance-transmutation, so said the knower of scriptures. (156)
By the touch of smoke, metals become gold and silver. That is known as smoke-transmutation, for certain, of the King of Mercury. (157)
From the bound mercury, by direct touch, the essence arises. The transmutation that arises from that is called sound-transmutation. (158)

Now the eighteenth act, the consumption of mercury, is told here by me with effort and in detail. (159)
