If we regard the gradation of worlds or planes as a whole, we see them as a great connected complex movement; the higher precipitate their influences on the lower, the lower react to the higher and develop or manifest in themselves within their own formula something that corresponds to the superior power and its action. The material world has evolved life in obedience to a pressure from the vital plane, mind in obedience to a pressure from the mental plane. It is now trying to evolve supermind in obedience to a pressure from the supramental plane. In more detail, particular forces, movements, powers, beings of a higher world can throw themselves on the lower to establish appropriate and corresponding forms which will connect them with the material domain and, as it were, reproduce or project their action here. And each thing created here has, supporting it, subtler envelopes or forms of itself which make it subsist and connect it with forces acting from above. Man, for instance, has, besides his gross physical body, subtler sheaths or bodies by which he lives behind the veil in direct connection with supraphysical planes of consciousness and can be influenced by their powers, movements and beings. What takes place in life has always behind it pre-existent movements and forms in the occult vital planes; what takes place in mind presupposes pre-existent movements and forms in the occult mental planes. That is an aspect of things which becomes more and more evident, insistent and important, the more we progress in a dynamic yoga.
But all this must not be taken in too rigid and mechanical a sense. It is an immense plastic movement full of the play of possibilities and must be seized by a flexible and subtle tact or sense in the seeing consciousness. It cannot be reduced to a too rigorous logical or mathematical formula. Two or three points must be pressed in order that this plasticity may not be lost to our view.
First, each plane, in spite of its connection with others above and below it, is yet a world in itself, with its own movements, forces, beings, types, forms existing as if for its and their own sake, under its own laws, for its own manifestation without apparent regard for the other members of the great series. Thus, if we regard the vital or the subtle physical plane, we see great ranges of it, (most of it), existing in themselves, without any relation with the material world and with no movement to affect or influence it, still less to precipitate a corresponding manifestation in the physical formula. At most we can say that the existence of anything in the vital, subtle physical or any other plane creates a possibility for a corresponding movement of manifestation in the physical world. But something more is needed to turn that static or latent possibility into a dynamic potentiality or an actual urge towards a material creation. That something may be a call from the material plane, e.g., some force or someone on the physical existence entering into touch with a supraphysical power or world or part of it and moved to bring it down into the earth-life. Or it may be an impulse in the vital or other plane itself, e.g., a vital being moved to extend his action towards the earth and establish there a kingdom for himself or the play of the forces for which he stands in his own domain. Or it may be a pressure from above; let us say, some supramental or mental power precipitating its formation from above and developing forms and movements on the vital level as a means of transit to its self-creation in the material world. Or it may be all these things acting together, in which case there is the greatest possibility of an effective creation.
