"Whoever you are, Oh you, who wish to probe the secrets of nature, if you do not find within yourself that which you seek, neither shall you be able to find it outside. If you ignore the excellencies of your own house, how do you intend to find other excellencies? In you is hidden the treasure of treasures. Oh, man, know yourself and you shall know the Universe and the Gods!" - Inscribed in the ancient Temple of Delphi.
