“Omnia ab Uno” is one of the mottoes of the Rosicrucians. It expresses the idea that the All has been evolved from One; or, in other words, that God is one and indivisible, and that the multifarious activities of life which we see in the universe are merely various forms of manifestations of God; or, to express it more correctly, of the creative Power, the Light and sunbstance of Life which emanated from the eternal cause of all existence in the beginning of our day of creation, and which has been called the Logos, the Verbum or Word, the Christ. As the Universal One manifested itself, it assumed various aspects, and it therefore appears as a great variety of powers and as innumerable forms of various substances although all powers and substances are essentially and fundamentally one. The various terms used in occult science are con- sequently not intended. to describe powers and principles radically different from each other. but merely the various aspects of the one universal principle; and as the aspect of things changes according to the point of view from which they are considered, consequently a name applied to a power, if considered from one point of view. may not be applicable if the same principle is considered from another point of view. Likewise the four sides of a pyramid originate in one point and end in one, each side appearing to have a distinct individuality of its own. The higher we rise towards the summit, the more does this differentiation disappear, and the more does the Unity of all things and their identity with each other become apparent, until all difference is again absolved in the ultimate One. He who knows the One knows All; he who believes to know many things knows nothing. The One is the starting-point for all occult science. - Secret Symbols Of The Rosicrucians, c. 1888 by Franz Hartmann
