We ask the leaf, "Are you complete in yourself?" And the leaf answers, "No, my life is in the branches." We ask the branch, and the branch answers, "No my life is in the root." We ask the root, and it answers, "No my life is in the trunk and the branches and the leaves. Keep the branches stripped of leaves, and I shall die," So it is with the great tree of being. Nothing is completely and merely individual.
