I have been scratching around for a while trying to find a comprehensive book or tutorial on the subject of using astrology to time your rituals. I have some general ideas in this direction, retrograde planets, planetary hours and days, houses and aspects etc, but I have to confess that some of the finer points of using astrology to empower your rituals and find the most auspicious time is not firmly grasped in my mind.
Can anyone offer advice, book recommendations or point me towards an online tutorial?
Many thanks in advance

Janice.
