Sigils are the means of guiding and uniting the partially free belief with an organic desire, its carriage and retention till its purpose served in the sub-conscious self, and its means of reincarnation in the Ego. All thought can be expressed by form in true relation. Sigils are monograms of thought, for the government of energy (all heraldry, crests, monograms, are Sigils and 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 on that particular desire (at the magical time), escaping the detection of the Ego, so that it does not restrain or attach such desire to its own transitory images, memories and worries, but allows it free passage to the sub-consciousness.
