The divine Spirit is known by the mystics of all ages as the sun; and therefore in all ancient mystical symbols the sun has been pictured as the sign of God. This conception gives one a help in the further knowledge of metaphysics. This sun is that aspect of Absolute God in which God begins to manifest, and His first step towards manifestation is His contraction, that contraction which is seen in all living beings and in all objects. It is first contraction that takes place, and next expansion, which comes as a matter of course, as a reaction. The former tendency is the desire of inhalation, and the latter exhalation. The contraction and expansion which are seen in all aspects of life come from God Himself.
