Alchemy is an occult science based upon the crafting of the Philosopher’s Stone, which allows the transmutation of base metals. The ability of the alchemists to turn lead into gold ensured the popularity of this spiritual discipline, but also painted the wrong picture. Indeed, turning lead into gold is just a means, not an end. The true goal is a process of self-improvement. The ultimate goal of alchemy is thus the inner transformation of the alchemist.
