“Medieval Alchemists, Who Searched for the Secret of Matter in a Prescientific Way Hoping to find God in it, or at Least the Working of Divine Activity, Believed that this Secret was Embodied in Their Famous
“Philosopher’s Stone ” but Some of the Alchemists dimly perceived that Their Much-Sought-After Stone was a Symbol of Something that can be Found Only with the Psyche of Man.”

~ Carl G. Jung, Man and His Symbols (1875-1961)
