The Hermetic Stone

As such, within a Hermetic context, we are not looking for a physical stone; the stone represents our body. In fact, it was the Italian philosopher Julius Evola in “The Hermetic Tradition” (1931), who discussed this very notion and who offered an insight into the true nature of the Grail – an insight, it has to be said, which has illuminated few since.

In short, the Grail is also the Philosopher’s Stone and we don’t need to look far to find it; perhaps it is so close, that we don’t see it: our mind is living inside of it – our body – and it is the task of those who want to find the Grail, to transform body and soul, make the two one. That, again, was the task of the Hermeticist and the true Grail Quest.

“This is stone and not stone, it is found everywhere, is base and precious, hidden and visible to everyone.”

“Visit the interior of the earth and rectifying (i.e. purifying) you will find the hidden/secret stone”.

And this is the Gold hidden in Saturn.
