Rene Guenon's book “Multiple States of Being” is devoted to the most important metaphysical issues. Here we consider such concepts as the Absolute, manifested and unmanifested, conditioned and unconditioned, Being and Non-Being, Possibility, Infinity, freedom, universal Existence. This book provides the key to understanding Guenon's entire metaphysical and esoteric concept; it is central to his entire work. Here, not only the basic concepts and terms themselves are carefully and in detail explained, but also their connections and relationships in the integrity of his teachings. The second book included in this edition, “Traditional Forms and Cosmic Cycles,” contains cosmological knowledge inherent in the eternal tradition. The combination of two books in one volume is justified by the fact that the first represents the metaphysical principle itself, and the second its application to the knowledge of the universe with all its depth and mystery.
