The term is also used to describe the spiritual practices of chemists from other ancient cultures, such as ancient Chinese "alchemists." In the old days, there was no division seen between spiritual and physical practices, but for the sake of modern obsession with duality, alchemy can be divided into two types. Practical alchemy is chemistry, studying nature and manipulating the properties of matter to get what you want out of the universe. Spiritual alchemy is a form of mysticism and spiritual self-improvement with analogies to chemical jargon, such as “turning base metals into gold”. “Gold” refers to the state of spiritual perfection, while the lesser “base” metals, such as lead, is an analogy to the impure states of the spirit, unenlightened and full of the problems of mortal life.
While alchemy could empower its practitioners to create new solutions to timely problems, an alchemist’s mind could be inspired towards philosophy and political ideals, educational systems, or medicinal concoctions. When it came to medicines, some alchemists would choose to work with herbs and organic formulas, while others preferred the world of inorganic elements, such as stones and their silent powers.
Passed down from generation to generation, the occult knowledge of the magnetism and resonance of stones has been kept by some, for the benefit of all.
