It is a sign that the student is performing this correctly when a single "Vibration" entirely exhausts his physical strength. It should cause him to grow hot all over, or to perspire violently, and it should so weaken him that he will find it difficult to remain standing.
It is a sign of success, though only by the student himself is it perceived, when he hears the name of the God vehemently roared forth, as if by the concourse of ten thousand thunders; and it should appear to him as if that Great Voice proceeded from the Universe, and not from himself.
Soror Marfiza's Notes
The Divine Names are generally pronounced as follows:
The names of the Archangels have these meanings:
There is a certain amount of variation in actual practice of this ritual. For example, some touch the genitals when saying "Malkuth". It is written that Crowley used to form the middle pillar on his body with "Ateh" at the forehead, "Aiwass" at the breast, and "Malkuth" at the genitals. Some say AUMGN instead of AMEN. And in the vibration of the Divine Names, some intone them, some shout them, some whisper them, and some "vibrate" them as described in Liber O.
Many Thelemites choose, in rituals such as the Rites of Eleusis and others, to substitute Liber XXV, called The Star Ruby, for this ritual.
