"An idle man will never become a magician. Magic is an exercise of all hours and all moments. The operator of great works must be absolute master of himself; he must know how to repress the allurements of pleasure, appetite and sleep; he must be insensible to success and to indignity. His life must be that of a will directed by one thought and served by entire Nature, which he will have made subject to mind in his own organs, and by sympathy in all the universal forces which are their correspondents."

- Eliphas Levi
