This volume by the Master Omraam Mikhaël Aïvanhov is not an astrological handbook. The Zodiac here discussed is the Book of Books in which everything is recorded, and the constellations and planets are the hieroglyphs, the sacred letters which reveal, to those who know how to decipher them, how mankind and the world were created, how they evolve hand in hand and how their inner structure is identical. Every human being who becomes aware of his kinship with the universe begins to feel the need to cultivate his inner life in order to rediscover, within himself, that cosmic plenitude symbolized to perfection by the circle of the Zodiac.
