When we don't listen, we are shutting ourselves off -- not from others but from ourselves. We can't do anything from a place of knowing. When we think we know something, we don't listen. We have to empty ourselves over and over, return to unknowing, and just listen. And listen. And listen... And once we listen, we have to act. The functioning that comes out of listening -- out of "Attention!" -- is compassionate action. If we don't listen, we can't act with compassion.
A powerful meditation when contemplating the oneness of everything is to find something's unique qualities. For example, observing an island's wholeness and then focusing upon the uniqueness of a single stone. . . . this meditation is simple but powerful. . . . Other examples to meditate upon (other than an individual stone on the island beach) are faces in a crowd or a leaf on a tree. Each person (in the crowd) is unique and yet (at that very moment) part of the whole. The same is true for leaves on the trees. Practicing this deceptively easy meditation helps each of us to see reality.
