This account of the science and art of astrology teaches that a good and true astrologer is not a fatalist, a helpless automaton in the hands of a merciless Fate, but turns instead toward self-exertion and self-help. This ancient lore is to be practiced not for selfish ends, according to the author, but to guide the needy and the distressed, to remove the cause of their suffering and turn their attention toward God.
