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.
To nourish the soul means to become kinder, more compassionate, wiser, and more loving, often through the making of difficult choices that foster growth rather than safety. The nourishment and growth of the soul is very reason for human life. When we nourish the soul we nourish God, increasing the abundance of the life that we can see – our children, or society – and the levels of life we don't see at all. In a larger sense, soul is the substance of the universe, knowing itself and growing itself.
