The Sorcerer's Apprentice

Rudolf Steiner: "What then is the Holy Grail? For those who understand this legend correctly, it signifies--as can even be proved by literary means--the following. Till now, man has only mastered the inanimate in nature. The transformation of the living forces, the transformation of what sprouts and grows in the plants, and of what manifests itself in animal and human reproduction--that is beyond his power. Man has to leave these mysterious powers of nature untouched. There he cannot encroach. What results from these forces cannot be fully comprehended by him."
