Silence as a spiritual practice is much more than being able to sit still without talking for thirty minutes or longer. Instead, silence is a quality of presence. The silence we search for is an overall state of being. It is not something we achieve with great effort, either, but something we uncover that is inside us. Somewhere at our core there is a reservoir of silence. . . . To return regularly to this depth, whether in cloistered silence or in line at the grocery, is called "a habit of silence." It is not duration that is important, but the returning time after time to the source within us that, in time, shapes who we are.
A human being is part of the whole, called by us the "universe," a part limited in time and space. One experiences oneself, one's thoughts and feelings, as something separated from the rest, a kind of optical delusion of one's consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the Oneness of nature in its beauty.
