9This is the introductory volume to Gargatholil's 4-volume work, Depth Astrology: An Astrological Handbook--the first comprehensive handbook for the interpretation of planetary positions (in signs, houses and aspect to each other) written from a depth astrology perspective. Here, Gargatholil explains the theory and philosophy behind depth astrology, a psycho-transformative approach to chart interpretation, and his treatment of the astrological symbol-set. For those new to astrology, or to the field of depth astrology as exemplified in the works of such pioneers as Dane Rudhyar, Liz Greene and Stephen Arroyo, Gargatholil provides a basic guide to the astrological symbol-set. Essential meanings are discussed for each of the planets, signs, houses, aspects, elements and modalities.Other volumes of this set are: Planets in Signs, Planets in Houses and Planets in Aspect. Depth Astrology has been reviewed in The Mountain Astrologer, Dec/Jan 2018 issue.
