The Jewel Mine of Mercury

...those which are Jayantī, Varāha, Mūka, Kakuranṭaka, Kośātakī, Kārivella, Lāṅgalī, Sahadevikā, Cakramarda, Mayūraka, Vācoravipriyā, Viṣṇukāntā, Hastasuṇḍī, Sukudyora, Bhṛṅgarāja, Paṭu. These are the herbs declared; one should use them in the killing fixing of mercury. These, or all of them together, should be given as purifiers of mercury. Pounded in the urine of an un-calved cow, and having reached a smooth state, mercury is dried by their decoctions; joined with equal parts of sulfur, one should grind it in a mortar for four yāmas 12 hours. Having smeared it, place it in an apparatus, and perform a Mahāpuṭa great heat process. In this way, with seven puṭas rounds of heating, grind and grind again and again. Then, in a Vajramuṣā diamond crucible, put eight-fold parts and cook in a Bhūdhara earth-cased puṭa. By this, it becomes ash. With juices, grind again and again; this mercury-ash is successful. Mercury killed by herbs is free from the fatigue of Jāraṇa digestion/absorption. ... Grind with twice the amount of mercury-sulfur oil for one day. With the juices of Kātha, Sarpākṣī, Viṣṇukāntā, and Bhṛṅgarāja, grind well and cook... In this way, eight times, the mercury ash is surely produced. With Śvetakolī and Rudrajaṭā, grind the mercury.

...three times, heat in a Bhūdhara-puṭa. One obtains the ash. With Devadālī and Harikāntā, grind with Māra-nāla. With those juices, seven times, one should make the mercury faint process it. Give that mercury in a Kharpura earthen basin... like salt, the ash shall be.
