"The mind is a machine - a thought machine. It produces thoughts all day and thoughout much of the night. We experience these endless thoughts in our awareness. The mind itself is not awareness. It is only a machine. We are the awareness. This points to an interesting possiblity. If we can bring the thought machine, the mind, to rest, what will we experience? It will be our awareness, our self, minus the incessant activity of the mind. This is what meditation is for, and the consequences of this are far-reaching."
