Surrender
When you are disciplined by yourself, you are surrendering to yourself. It is, as I explained, you don't surrender to somebody else. It is surrendering to your own higher Self. When I make a plan, I discipline my mind so that it is not free in the common sense that it can do what it likes. Surrender is the proper utilization of your capacity.
