There is nothing to practice. To know yourself, be yourself. To be yourself, stop imagining yourself to be this or that. Just be. Let your true nature emerge. Don’t disturb your mind with seeking — Sri Nisargadatta Maharaj
An insight into the true nature of the principles of alchemy and the teachings of Hermes Trismegistus (also known as Thoth, Mercury, or Hermes in different cultures).

Alchemy is not all about transforming things into gold, but more of a understanding of the true nature of things and how to manipulate their energies. This is highly esoteric information.
