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.
If we just worry about the big picture, we are powerless. So my secret is to start right away doing whatever little work I can do. I try to give joy to one person in the morning, and remove the suffering of one person in the afternoon. If you and your friends do not despise the small work, a million people will remove a lot of suffering.
