Ricavo dalla scheda online di Yesterday's Muse, bookseller americano: "A collection of short essays on various topics, written from the perspective of esoteric Christianity. Topics include astral healing, alchemy, the spirit realm, astrology, subliminal and supraliminal consciousness, and an early discussion of birth control".
Esemplari (fra l'altro): Libray of Congress.
