Sigil

An abstract glyph constructed by a magical practitioner from a written statement of intent, then charged through a state of gnosis to release the intent into the unconscious. The technique was developed by Austin Osman Spare in The Book of Pleasure (1913) and became the central technical innovation of chaos magick from the late 1970s onward. The standard method removes vowels and repeated consonants from the statement, then composes the remaining letters into a unified glyph.
