Out of a friendship and collegial conversation spanning three decades, Hadley Fitzgerald and Judith Harte have created a provocative fusion of astrological symbolism, Depth Psychotherapy, and Imaginal Psychology. Their discourse interfaces with the "acorn theory" of the late archetypal psychologist James Hillman who conjectured that each life has its own soul's code, its own calling. The authors see this as resonant with a natural, yet sophisticated astrology wherein the horoscope's trajectory is viewed as a pathway to one's personal archetypal ground. They suggest that we can evolve in the direction of our own life's calling by viewing the horoscope as analogous to an acorn, inside of which is one's unique soul's code with a mysterious timepiece all its own. As licensed psychotherapists who are actively engaged in the arts, they often use images, imaginal dialogue, and evolutionary astrological methods to deepen their clients' psychotherapeutic processes.
