In Liber Null, Peter Carroll talks about the "Alphabet of Desire".
The basis of the Alphabet of Desire (which was originally a concept from the work of A. O. Spare), is that every emotion (apart from Laughter, which is it's own opposite), follows a dual pattern. Learning to ride these emotions, by exploring the Alphabet Of Desire allows the magician to be in control of these emotions, rather than at their mercy.
The main forms of duality (which are then expanded into principles) being: Sex/Death, Love/Hate, Desire/Fear, Pleasure/Pain, Elation/Depression.
Peter Carroll gives for each of these twenty one principles, a picture (glyph) and a brief textual description, along with some correspondences (planetary, alchemical etc).
I have started creating my own Alphabet of Desire, allowing my unconscious mind to bring fourth a picture for each principle, and then picking a Tarot card that represents that particular emotion for me. I believe it's important for every magician to create their own Alphabet of Desire, as ultimately we are dealing here with our own unconscious mind and emotions, and it could become a powerful magical tool for emotional engineering. I hope to publish a more detailed write up on my website at a later date.
