Astrology provides structures that allow us to create a map of the soul's life. The contents of these structural patterns are of a psychological or social nature. There are four basic needs upon which the diverse processes of organic life are based. Dane Rudhyar demonstrates in this book in a very impressive way that the fundamental human functions are related to the planetary pairs of Saturn and Moon, Jupiter and Mercury, as well as Venus and Mars. If you consider the planets as a symbolic correspondence to these fundamental principles, you will quickly recognize where the meaning, purpose, and role of the individual lies in our universe.
