The book of the famous Russian astrologer Galina Nikolaevna Volzhina “The Nature of the Black Moon in the light of modern occult astrology” was written on the basis of more than twelve years of research. This work can rightly claim to be the most complete and comprehensive. The author tried not only to find, but also to substantiate answers to the most controversial questions arising around this little-studied phenomenon. The phenomenon of the Black Moon is examined in the book from the perspective of occult philosophy, psychology, astronomy and astrological symbolism. The difference between the true and average coordinates of this fictitious point, the peculiarities of the “behavior” of the Black Moon in critical degrees, its connection with the lunar nodes and much more are discussed. There are chapters devoted to ancestral karma, synastry and other interesting problems. The book can be useful not only to professional astrologers, but also to students of astrological schools, as it contains a detailed analysis of practical examples that can serve as an excellent teaching aid. The author expresses his thoughts in clear language, which makes the book accessible to readers of different skill levels.
