Carter also teases us with his unpublished system of numerology, which was based on 12, rather than the usual 10. As astrology is based around the numbers 2, 3, 4 and 12 (not 5 or 10), a base-12 number system is of immediate interest.
Realizing his subject was abstract and unlikely to appeal to all, Carter also includes innovative ideas on directing, and on transits. The result is a book that fascinates on many levels.
Carter's books, penetrating & full of unique insights, are ideal for intermediate & advanced astrologers. They are, in fact, virtually in a class by themselves. Carter's books are organic wholes. He shows how individual astrological factors combine to create living, breathing people. It is this constant interplay of factors, and Carter's brilliant, lucid exposition, that makes his books so precious.
