Sacrament
"Now in this is the magical power known. It is like
the oak that hardens itself and bears up against the storm. It is weather-beaten
and scarred and confident like a sea-captain. Also it straineth like a hound
in the leash. It hath pride and great subtlety. Yea, and glee also! Let the
Magus act thus in his conjuration;
Let him sit and conjure; let him draw himself together in that forcefulness;
let him rise next swollen and straining; let him dash back the hood from his
head and fix his basilisk eye upon the sigil of the demon. Then let him sway
the force of him to and fro like a satyr in silence, until the Word burst
from his throat.
Then let him not fall exhausted, although he might have been ten thousandfold
the human; but that which floodeth him is the infinite mercy of the Genitor-Genitrix
of the Universe, whereof he is the Vessel."
(from "Liber A'ASH vel Capricorni Pneumatici" by
Aleister Crowley)
