Book excerpt: The book 'Esoteric Islam' discusses the mystical teachings of Quran from the standpoint of ancient mysteries and modern metaphysics. The Quran is considered as the book of divine guidance by Muslims whose main subject constitutes ‘man’. From a hermetic standpoint, the Quranic mysteries carry a great deal of connection to the hermetic arts of astrology and alchemy. Here, I have attempted to explain the manner in which symbolism of the hermetic precepts can be used to understand the Quran in its structural designs alongside the principle tenets, so as to define the notions of highest aspirations in men, and to unravel the mystique of this very impressive literature.
