Spiritual Force

Leave aside the question of Divine or undivine, no spiritual man who acts dynamically is limited to physical contact—the idea that physical contact through writing, speech, meeting is indispensable to the action of the spiritual force is self-contradictory, for then it would not be a spiritual force. The spirit is not limited by physical things or by the body. If you have the spiritual force, it can act on people thousands of miles away who do not know and never will know that you are acting on them or that they are being acted upon—they only know that there is a force enabling them to do things and may very well suppose it is their own great energy and genius.
