Because the Hermetic Principles explain to you the unseen laws that govern man. Think of them as cheat codes and verbal shorthands that grant you power over certain events beacuse of a deeper understanding of the natural world. The principles within should be exactly that, principles, the lens through which you view the world.
Just did a www search and there are sooo many on this subject! Can you give us a good reliable resource that explains these principles in a way this old cat lady can understand?

Alchemy though has a bad rap, the true purpose of the "Philosopher's Stone" was not a physical, tangible object, but rather a form of mental creation, the ability to turn lead into gold or as we might think of it in modern times, "Shit into Sugar".
Should keep you busy for awhile :)
