The power of silence lies in its emptiness. Silence is a receptive space. It creates a sacred void, an opening through which you can receive: truth, perspective, strength, healing, revelation. In silence, you transcend words and contact the wordless. You fill up with a peaceful knowing. Silence is not the same as prayer. Prayer is a way of directing your feelings and thoughts, focusing them and sending them toward a source. Silence is listening, receiving, being. One is trying to reach the source of communication with it; the other, silence, is allowing yourself to hear the source within yourself, to become one with it... In prayer, you are the sender; in silence, you are the receiver.
We are all in this together. So when you realize that you're talking to yourself, label it "thinking" and notice your tone of voice. Let it be compassionate and gentle and humorous. Then you'll be changing old stuck patterns that are shared by the whole human race. Compassion for others begins with kindness to ourselves.
