21: "Hence every manifested God is spoken of as a Trinity.  The joining of these three Aspects, or phases of manifestation, at their outer points of contact with the circle, gives the basic Triangle of contact with Matter, which, with the three Triangles made with the lines traced by the Point, thus yields the divine Tetractys, sometimes called the Kosmic Quaternary, the three divine Aspects in contact with Matter, ready to create.  These, in their totality, are the Oversoul of the kosmos that is to be.
"Under Form we may first glance at the effects of these Aspects as responded to from the side of Matter.  These are not, of course, due to the Logos of a system, but are the correspondences in universal Matter with the Aspects of the universal Self.  The Aspect of Bliss, or Will, imposes on Matter the quality of Inertia-Tamas, the power of resistance, stability, quietude.  The Aspect of Activity gives to Matter its responsiveness to action—Rajas, mobility.  The Aspect of Wisdom gives it Rhythm—Sattva, vibration, harmony.  It is by the aid of Matter thus prepared that the Aspects of Logoic Consciousness can manifest themselves as Beings."—A Study in Consciousness, by Annie Besant, p. 9.
