I wanted to share a story I just read from "The book of Alchemy" by Francis Melville.
A scientist who was engaged in nuclear research in 1937 was visited by a person named Fulcanelli, as part of their discussion, asked the Alchemist about the nature of his work.
Fulcanelli replied "You are asking me to summarize in four minutes four thousand years of philosophy and my whole life's work, furthermore you are asking me to translate into plain words concepts for which such a language is not intended. All the same I can say this: you will not be aware that in present-day official science the part played by the observer becomes more and more important. Relativity, the principles of indeterminacy, demonstrates the extent to which the observer today intervenes in all these phenomena."
"The secret of Alchemy is this: there is a way of manipulating what modern science calls force-field. This force-field acts upon the observer and puts him in a privileged position, he has access to the realities which are normally concealed from us by time, space, matter, and energy. This is what we call The Great Work"
The scientist asks "But what of the Philosophers Stone? And the making of Gold?" Fulcanelli replied "Those are only applications of it, particular cases. The vital thing is not the transmutation of metals, but that of the experimenter themselves. It is the ancient secret that a few people re-discover each century."
