We need to "stop" but what does it mean to do that? It only ever happens in one of two ways.
1: Something shocks me and it "stops me in my tracks". That is temporary. It never lasts and I generally feel a sense of relief when it passes.
2: I do it as an act of will through a conscious breath. Doing it this way also gives a sense of relief but it's different. It's relief from the illusion created by my thinking.
That's what the "stop" is and that is where my true life can begin. By stopping my thinking and letting stillness embrace the whole of my being. The illusion melts away for just a moment. I am.
