This book provides a penetrating, sensitive, poetic, and visual insight into the twelve qualities required for the spiritual life, for astrologers and non-astrologers alike. Using the Astrological signs and houses, Rudhyar builds a framework for impregnating the seeker with an awareness of how to use basic life challenges, as a process through which an individual human being evolves. Twelve exquisite artistic renderings evoke the archetypal, intuitive level of each sign.
