The book, "Spiritual Alchemy", written by , C.C. Zain, is full of easy to understand alchemical terminology. The author easily explains The Philosopher's Stone, Transmutation, The Elixer Vitae, The Great Work, and Higher states of Conciousness. Bear in mind, this is a course textbook written by a Master Initiate for his students. But it may be enjoyed by all who share a love for The Western Esoteric Tradition. It is a wonderful treatise on esoteric lore and has my highest recommendation. Buy it today!
