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 thirst for God, the desire for unitive knowledge, is not something foreign to our nature. This desire is already in the human heart; the only reason we fail to perceive it is because it is usually covered up with petty worries and egotistical ambitions. Once these are removed, the true desire, buried in the deepest recesses of the human mind, will shine forth of itself and, like a flame, will leap toward heaven, which is its true Home.
