The inner planets—Mercury, Venus, Mars—are the foundations of what psychology calls the ego, the sense of personal self. In this fourth volume in the Seminars in Psychological Astrology series, Liz Greene and Howard Sasportas discuss the value of the inner planets as they symbolize important aspects of personality. We are not trained to give value to our private needs, feelings, and qualities. Indeed, because of their intensely personal nature, they are often suppressed or overlooked as irrelevant to society. Likewise, the inner planets have tended to be given less attention by psychological astrologers—for they are the personal planets. The authors show us that in order to give the most that we can to our interactions with the rest of the world, we must first understand our own needs and have a healthy ego— a personal authenticity. Their book teaches us the process of understanding how these three planets actually represent our individuality, and how they directly color the energy of the rest of our horoscope. Greene and Sasportas blend the processes of astrology and psychology in a unique and important way in this in-depth insight into the archetypes represented by the inner planets.
