Cultivating awareness is an essential discipline for being in the moment. As awareness deepens we become more receptive; we gradually discover the life process and move from the quantified aspects of things to their qualities. We perceive ourselves less as observers and more as integral parts of the process. Awareness leads to the sure knowledge that we are creatures among creatures and that the earth is always aware of our presence. Awareness cannot be realized without solitude and silence. Solitude enables us to become aware of the boundaries of the self, to experience aloneness as a prelude to the experience of at-one-ness. To be silent is to let go of that fear which drowns out every kind of awareness. Silence leads us into mystery. Silence means stilling self-reflexive chatter and adopting an attitude of listening. Listen to the silence of the earth -- it is deafening. Listening to the silence of earth brings us into communion with every separate being -- a blade of grass moving in the breeze, an ant walking across a leaf, the eagle hovering high overhead, water flowing slowly from a hidden spring. One becomes an ear so that all might become music.
Silence has many dimensions. It can be a regression and an escape, a loss of self, or it can be presence, awareness, unification, self-discovery. Negative silence blurs and confuses our identity, and we lapse into daydreams or diffuse anxieties. Positive silence pulls us together and makes us realize who we are, who we might be, and the distance between the two. Hence, positive silence implies a choice, and what Paul Tillich called the "courage to be."
