To awaken means to realize one's nothingness, that is, to realize one's complete and absolute mechanicalness, and one's complete and absolute helplessness. And it is not sufficient to realize it philosophically in words. It is necessary for us to realize it in clear, simple and concrete facts, in our own facts.
Until we reach the stage of realizing our own nothingness, we cannot change. To begin to realize one's own nothingness as a practical experience is to begin to cease identifying with oneself.
Silence is really vital for the human heart. You see, the human heart can't live with constant sound or noise. It needs silence in order to heal itself. The only two things that are ultimately required for spiritual homecoming are stillness and silence. If, into your day, you can build little windows of silence and little windows of stillness, you will never lose touch with your deepest voice. You will never lose touch with your most secret belonging. Even though you walk and talk and act in the world, you will never leave the inner, tender home of your own soul.
