teachings of Thelema Lodge

"Throughout the text of 777 will be found the Hebrew names of countless intelligences, spirits, genii, angels, and other Yetziratic and qliphotic denizens. In order to work with such entities, it is often helpful to be able to create a form that will be the object of sustained visualization during workings. The form built up is constructed of the imaginative yetziratic faculties -- the astral light.  It is into this form that the force is compelled to indwell for the duration of such rival practices.  Many of these beings have no traditional forms catalogued, and so it is left up to the individual magician to construct talismatic images.  This may be accomplished by means of the yetziratic attributions of the Hebrew alphabet.  Each letter has associated with it certain qualities of talismatic imagery; thus, by taking the letters of a spirit's name, one may build up a suitable vehicle in the astral light.  This practice may be applied to other languages which have yetziratic values associated with the letters; Greek is a classic example, and many magicians have constructed talismatic images of the four beings invoked in the Star Ruby, for example.  Take the name of the being and write it vertically, from the top down.  The first letter will generally give the qualities of the head, the next of the torso, and so on down to the feet. This is a practice where the artistic abilities of the magician will come into play, as intuitive associations will help to build up the imagery based upon qabalistic guidelines."
