When and at what time the Divine Genius invites or secretly prompts the Understanding to curious Notions, observe that time (viz. the Ascendant of the Figure of Heaven for that moment) and how the Moon applies; for whatever concerns those Notions must be farther agitated, written, or studied when the Moon is in a Sextile, or rather a Trine Aspect to that sign she was in at that time, and if possible, with that Planet who was then Patron or proper Significator of those conceptions, and this is something near attaining Prophesy, if rightly understood. Above all things serve God: Astrology is attainable by prayer and industry, especially by such a person that hath a natural propensity to the study thereof. These Notions were write without any assistance or inspection of a Book, and will bear or require a Commentary thereupon. - William Lilly (1602.-1681.)
