Rasaratnākara (Rasāyanakhaṇḍa)

When the mercury is free of foam and smoke and becomes smokeless, (207) salute the moon, sun, planets, stars, deities, and worlds, and salute the teacher and god; then place the body the mercury preparation there. (208) Know it to be well-melted and pour in the earthly mercury. (209) Blow on it with effort until it turns red. Add the mercury known as "non-essence" to it, and it will become red. (210) Add air-combined mercury, and it will become white-colored. Add fire-combined mercury, and it will become fire-like. (211) Then add sky-combined mercury to it. Once turned, it becomes gold-like; place it there. (212) Then add the divine life-combined mercury and utter the huṃ sound. Make a great noise there combined with the three huṃ sounds. (213) Then the siddha perfected being arises, as the sun in the forenoon. (214) With divine radiance, a great body, and great strength and valor, (215) his strength exceeds that of nine thousand snakes. He lives with a diamond-body; this is the truth spoken by Śiva. (216) For those withered by age, the blind, the lame, the lepers, (217) the speechless, the dull, the hunchbacked, and the diseased, (218) for those suffering from many illnesses, the exhausted, the insane, and the possessed, (219) what is more to be said for those of clean bodies, the kings, and the mercury-practitioners? (220) For heroes and seekers, it grants divine perfection. Therefore, he who is a practitioner here is undoubtedly Bhairava. (221) He becomes a siddha with a diamond-body, wise and possessing a divine form. (222) A vehicle vimanā half a yojana approx. 4 miles wide, accompanied by heavenly nymphs, (223) arrives without doubt in front of that siddha. (224) Mounted there, he plays in the realm of Rudra like Bhairava. (225) Freed from hunger and thirst, he does not perish at the destruction of the world. (226) Consuming all enjoyments, he becomes dear to the yogis.
