From the starting of the process of Involution from the Mental Principle, down to the extreme downward point of the grossest Manifestation of Matter, there were many stages. From the highest degree of the Finite Mind, down to lower and still lower degrees; then on to the plane of Force and Energy, from higher to lower degrees of Principle within Principle; then on to the plane of Matter, the Involutionary urge proceeded to work. When the plane of Matter was reached, it, of course, showed its highest degree of manifested Matter--the most subtle form of Ether, or _Akasa_. Then down, down, down, went the degrees of Matter, until the grossest possible form was reached, and then there was a moment's pause, before the Evolutionary process, or upward-movement, began. The impulse of the Original Will, or Thought, had exhausted its downward urge, and now began the upward urge or tendency. But here was manifested a new feature. This new feature was "The Tendency toward Individualization." During the downward trend the movement was _en masse_, that is, by Principle as _Principle_, without any "splitting up" into portions, or centers. But with the first upward movement there was evidenced a tendency toward creating Centers of Energy, or Units of activity, which then manifested itself, as the evolutionary movement continued, from electrons to atoms; from atoms to man. The gross matter was used as material for the formation of finer and more complex forms; and these in turn combined, and formed higher, and so on, and on. And the forms of Energy operated in the same way. And the manifestations of centers of Mind or consciousness in the same way. But all in connection. Matter, Energy and Mind formed a Trinity of Principles, and worked in connection. And the work was always in the direction of causing higher and higher "forms" to arise--higher and higher Units--higher and higher Centers. But in every form, center or unit, there was manifested the Three Principles, Mind, Energy, and Matter. And within each was the ever present Spirit. For Spirit _must_ be in All--just as All must be in Spirit.
