Sigils are monograms of thought, for the government of energy (all hereditary crests, monograms, etc., are Sigils and represent the Karmas they govern), relating to Karma; a mathematical means of symbolising desire and giving it form that has the virtue of preventing any thought and association with that particular desire (at the magical time).The desire is thus protected from detection by the Ego, which cannot then restrain or attach the desire to its own transitory images, memories and worries, but allows it free passage to the unconscious.
