Merely do not limit awareness. It is always a sphere. That is the point where we are objectifying our content, rather than embracing it. So, whether we bounce off the floor, or we bounce off Frank, or we bounce off whomever or whatever, that is the point of objectification. If we are filled with doubts, there are limits everywhere.
Faith trusts the body of awareness rather than our interpretations of experience.
The person of faith who commits himself or herself to this practice will move much more smoothly than our smart, sophisticated, cynical minds, which know so much. We know so much, we know better, we know smarter, we know everything else. And, we really know how to create our own suffering. Such doubt puts up walls and floors as boundaries, people as objects. Our conventional view draws lines of division within our own consciousness.
