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.
The point of passing time in solitude is to strip yourself bare, to discover what is essential and true. When you are stripped down to this point, you see how little you amount to. But that little is what God is interested in.
