Those with heart attuned and breath toward the Divine read the Book of Nature as the conversation of That Which IS. The arms of the tree upraised lift one in praise; swept down, convey those blessings of Being. Toward the One, one moves, and the heart responds with the teachings and guidance of life.
The priest conveys the blessing when in selfless love; but when as the lesser self, acts as the barren tree - unable to give shelter. The blessings stopped through the person, but always present through the self-less-ness of nature.
