I. THE PRINCIPLE OF MENTALISM. "THE ALL is MIND; The Universe is Mental."-The Kybalion. This Principle embodies the truth that "All is Mind." It explains that THE ALL (which is the Substantial Reality underlying all the outward manifestations and appearances which we know under the terms of "The Material Universe"; the "Phenomena of Life"; "Matter"; "Energy"; and in short, all that is apparent to our material senses) is SPIRIT, which in itself is UNKNOWABLE and UNDEFINABLE, but which may be considered and thought of as AN UNIVERSAL, INFINITE, LIVING MIND.
