Sri Aurobindo next addresses the different scenarios that could lead to varying speeds of accomplishing the transformation of consciousness from the mental through the overmental to an eventual supramental basis of action, with all of the impact such a transformation would have on mind, life and body and life in the material world. He points out that it would be a long, slow and difficult process if there were no direct descent, or intervention, of the supramental force into material nature; and if all we had, then, was a pressure from above working to evolve the supramental action out of its involvement in the Inconscient here. Such a process would be limited by having to work through the mind, life and body and their restrictions, habits, impediments and differing principles of action. The end result would also be limited by virtue of the fact that mind, life and body have these differing principles of action and cannot be expected to totally transform themselves if they remain the basis and foundation of the evolved consciousness.
The faster and more effective solution would be for the supramental consciousness to actually descend and work directly in this world, putting in place a foundation and action of its own native and characteristic line of action and results.
“For a real transformation there must be a direct and unveiled intervention from above; there would be necessary too a total submission and surrender of the lower consciousness, a cessation of its insistence, a will in it for its separate law of action to be completely annulled by transformation and lose all rights over our being. If these two conditions can be achieved even now by a conscious call and will in the spirit and a participation of our whole manifested and inner being in its change and elevation, the evolution, the transformation can take place by a comparatively swift conscious change; the supramental Consciousness-Force from above and the evolving Consciousness-Force from behind the veil acting on the awakened awareness and will of the mental human abeing would accomplish by their united power the momentous transition. There would be no farther need of a slow evolution counting many milleniums for each step, the halting and difficult evolution operated by Nature in the past in the unconscious creatures of the Ignorance.”
