One must be.

In the creation of a new way of life, we must begin at the beginning, with our own individual regeneration. The formation of organizations, political bodies, religious bodies, social bodies is not enough. The trouble we see goes deeper than we perceive. The essential revolution must happen within ourselves. Everything depends on our attitude towards ourself – that which we will not affirm within ourself can never develop in our world. … "Be ye transformed by the renewing of your mind" is the ancient formula and there is no other. Everything depends upon man’s attitude toward himself. That which he cannot or will not claim as true of himself can never evolve in his world. Man is constantly looking about his world and asking, "What’s to be done? What will happen?" when he should ask himself "Who am I? What is my concept of myself?" If we wish to see the world a finer, greater place, we must affirm the reality of a finer, greater being within ourselves. It is the ultimate purpose of my teaching to point the road to this consummation. I am trying to show you how the inner man must readjust himself – what must be the new premise of his life, in order that he may lose his soul on the level he now knows and find it again on the high level he seeks.

A "now" which is "elsewhere" has for us no absolute meaning. We only recognize "now" when it is at the same time "here." When we feel ourselves into the desired state "here" and "now" we have truly changed our future.

Discouraged people are sorely in need of the inspiration of great principles. We must get back to first principles if we are to speak with a voice that will kindle the imagination and rouse the spirit. Again, I must repeat, in the creation of a new way of life, we must begin at the very beginning with our own individual regeneration. Man’s chief delusion is his conviction that he can do anything. Everyone thinks he can do – everyone wants to do and all ask, "What to do?" What to do?
It is impossible to do anything.
One must be.
It is hard for us to accept the fact that "We, of ourselves, do nothing." It is especially difficult because it is the truth and the truth is always difficult for man to accept. But, actually, nobody can do anything.
Truth will strip the clever pretenders of their false aristocracy. Truth, in its turn, will be conquered and governed by the aristocracy of goodness, the only unconquerable thing in the world.
Imagining Creates Reality.
Dare to Assume.
Assumptions become facts.
Neville started speaking and teaching in the late 1930's with concepts like these.
