Alchemy is a compound word. The first part is “Al”, which is related to the Arabic word for God, Allah or Spirit and that, of course, is closely related to the Hebrew term “El” which means God. “Chem” is derived from a Greek word “kimia” which means “to fuse or caste a metal.” Alchemy means “to fuse our metal with God”. The most important metal that we have within is Mercury, the symbol of sexual energy.
