The A-Z Horoscope Maker and Delineator, by Llewellyn George: probably the single best book for the novice astrologer. The caveat: this only applies to versions prior to 1980, when the publishers decided to remove 500 pages of pure astrology in favor of including information on the planet Pluto. In attempting to modernize or psychologize astrology, they ruined the book!
Astrology: a Cosmic Science, by Isabel Hickey: a good introduction to metaphysical astrology while still retaining a neoclassic feel. Every astrologer should not only own this book but refer to it frequently!
The Manual of Astrology, by Sepharial: another indispensable interpretive textbook in the neoclassic style.
Horary Astrology and the Judgment of Events, by Barbara Watters: though this is primarily about Horary Astrology, Natal Astrologers can learn much from this volume.
Horary Astrology Rediscovered, by Olivia Barclay: a new introduction to the classical Horary Astrology of William Lilly for modern practitioners. This is perhaps the one book that fostered the new interest in Traditional Astrology. Olivia devoted her life to the study of Lilly and was a master teacher and Horary Astrologer. One of my teachers whom I had the good fortune to meet and spend some time with… She is greatly missed.
Linda Goodman's Sun Signs, by Linda Goodman: though written for the masses this book contains some of the best descriptions of the Sun Signs available. I particularly recommend the sections entitled How to Recognize (fill in the sign). These sections will repay careful study.
Any book by Ivy Goldstein-Jacobson. These books are a gold-mine of astrological information gained from years of practice. They include many tips and techniques for the astrologer's toolkit.
Heaven Knows What, by Grant Lewi: this book comes with tables that allow anyone to cast their own horoscope and gives competent interpretations of character and potential. Exercise caution when it comes to the Moon's position, this should be calculated exactly based on your time and location of birth. But the interpretations are exceptional.
Astrology for the Millions by Grant Lewi: this volume deals mostly with the predictive aspects of astrology, particularly transits.
Any book by Charles Carter.
Any book by Vivian Robson.
From Pioneer to Poet, by Isabelle M. Pagan: or The 12 Great Gates; An Expansion of the Signs of the Zodiac Analyzed. A Theosophical approach to the Signs and their implications in the Nativity.
The Message of the Stars, by Max Heindel: An esoteric exposition of Natal and Medical Astrology explaining the arts of reading the horoscope and diagnosing disease. One of the textbooks for the Rosicrucian Fellowship’s Astrology course, presenting an interesting take on the “higher octave” planets (Uranus and Neptune and how they relate to Venus and Mercury respectively). Also by the same author: Astro-Diagnosis – A Guide to Healing.
Lectures on Medical Astrology, by Dr. William Davidson: a witty, thought-provoking introduction to Medical Astrology by a practicing homeopath. These can be very hard to locate. I believe these are so useful I am looking into republishing them myself. His teachings are incorporated into our Introduction to Medical Astrologycourse.
Conversations with God, by Neale Donald Walsch: perhaps the best introduction to metaphysics and Spirituality out there! Some people I know have felt irritated by Neale’s questions and/or personality as he was conversing with God… but if you look past that, the information he channeled is superior and internally consistent! Highly recommended!!
Any book by Paul Foster Case. His Tarot book will open new worlds for seekers with an open Mind and willing heart. Some of his material is very advanced, particularly The True and Invisible Rosicrucian Order, but well worth the meditation/contemplation.
Linda Goodman’s Star Signs, by Linda Goodman: based on a diary she kept while living in the mountains of Colorado. There are many nuggets of Wisdom to be mined from this book, and much esoteric food for thought.
The Life Everlasting, by Marie Corelli: a novel, but much more; an introduction to Rosicrucian concepts of Life, the Universe and everything including the oft misunderstood concept of Twin Souls, which Corelli expands upon in A Romance of Two Worlds. Well worth a read and some serious consideration.
The Kabala of Numbers, by Sepharial: an introduction to many systems and uses of Numerology. He includes planetary correspondences, colors, musical tones and methods of wagering based on his several different numbering systems.
Cheiro’s Book of Numbers, by Cheiro: the foremost explanation of the Chaldean System of Numerology. Linda referred to this book most frequently in her chapter on Numerology in Star Signs.
The Evolution Angel, by Todd Michael: an inspiring account of an ER physician’s encounters with the Divine. Highly recommended for anyone interested in Life, Death and that which is beyond. Also by the same author: The 12 Conditions of a Miracle and The Hidden Parables.
More to follow.
