"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.

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."
