"The deeper secrets and laws of our being are self-protected; to learn them requires an adaptation of character and purpose, and a humility of mind and spirit, inconsistent with those displayed by the perverse or merely curious enquirer. To understand, let alone practically to explore, the Hermetic Mystery is not for every one--at least, at his present state of evolutional unfolding. . . . Only to those whose spiritual destiny has already equipped them with a certain high measure of moral and intellectual fitness will even a rough notional apprehension of it be practicable."
- Mary A. Atwood, Hermetic Philosophy and Alchemy
