“Magic is the science of the ancient magi; and the Christian religion, which silenced the counterfeit oracles and put a stop to the illusions of false gods, does, this notwithstanding, revere those mystic kings who came from the East, led by a star, to adore the Saviour of the world in His cradle. They are elevated by tradition to the rank of kings, because magical initiation constitutes a true royalty; because also the great art of the magi is characterised by all adepts as the Royal Art, as the Holy Kingdom — Sanctum Regnum. The star which conducted the pilgrims is the same Burning Star which is met with in all initiations. For alchemists it is the sign of the quintessence, for magicians it is the Great Arcanum, for Kabalists the sacred pentagram.”

Context: From the earliest times man has been engaged in a search for general rules whereby to turn the order of natural phenomena to his own advantage, and in the long search he has scraped together a great hoard of such maxims, some of them golden and some of them mere dross. The true or golden rules constitute the body of applied science which we call the arts; the false are magic.

Vingt ans après (Twenty Years After) (1845)
Context: Learn ever to separate the king and the principle of royalty. The king is but man; royalty is the spirit of God. When you are in doubt as to which you should serve, forsake the material appearance for the invisible principle, for this is everything.
