Change is a fundamental element of consciousness. It is what calls our attention, awakens it, stimulates our questions. We see the red coat in contrast to the white snow... Without change, our minds become dull and unaware.
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.
