His student, a Siddha (immortal) named Bhoganātha is considered the father of alchemy. He used a combination of nine poisons (including mercury and sulfur), certain mantras, a breathing technique, and his immense lifeforce to transmute and stabilize a potion named Navapāśāṇa (Navapashana, Navapashanam are the colloquial terms) which is meant to cure diseases, extend life, etc. Several alchemists today claim to know this technique, but I am not convinced. Bhoganātha, before disappearing from public life, created an idol of Subrahmanya (the son of Shiva and the deity of sacral chakra) in a shrine at a place called Palani in Southern India, which exists to this day. Priests at this shrine bathe the idol with Panchamrita (milk appears bluish) and distribute it to people, who report miraculous cures after consuming this milk. This idol is extremely powerful and I could see the aura around the idol spread for miles and miles endlessly (in fact, right now, I was trying to focus on the idol and pay my respects to the deity and a surge of energy flooded me as the deity in this shrine is very awake unlike other shrines).
