THE EQUINOX night, and at sunrise. And if he be able, he shall pray also four times between sunrise and sunset. The prayer shall last for the space of an hour, at the least, and he shall seek ever to extend it, and to inflame himself in praying. Thus shall he invoke his Holy Guardian Angel for eleven weeks, and in any case he shall pray seven times daily during the last week of the eleven weeks. And during all this time he shall have composed an invo- cation suitable, with such wisdom and understanding as may be given him from the Crown, and this shall he write in letters of gold upon the top of the altar. For the top of the altar shall be of white wood, well polished, and in the centre thereof he shall have placed a triangle of oak-wood, painted with scarlet, and upon this tri- angle the three legs of the censer shall stand. Moreover, he shall copy his invocation upon a sheet of pure white vellum, with Indian ink, and he shall illuminate it according to his fancy and imagination, that shall be informed by beauty. And on the first day of the twelfth week he shall enter the chamber at sunrise, and he shall make his prayer, having first burnt the conjuration that he had made upon the vellum in the fire of the lamp. Then, at his prayer, shall the chamber be filled with a light insufferable for splendour, and a perfume intolerable for sweetness. And his Holy Guardian Angel shall appear unto him, yea, his Holy Guardian Angel shall appear unto him, so that he shall be wrapt away into the Mystery of Holiness. All that day shall he remain in the enjoyment of the know- ledge and conversation of the Holy Guardian Angel. 112
