Plants are the young of the world, vessels of health and vigor; but they grope ever upward towards consciousness; the trees are imperfect men, and seem to bemoan their imprisonment, rooted in the ground. – Ralph Waldo Emerson

Trees are much like human beings and enjoy each other’s company. Only a few love to be alone. – Jens Jensen, Siftings, 1939

Trees are the earth’s endless effort to speak to the listening heaven. – Rabindranath Tagore, Fireflies, 1928

It is not much for its beauty that makes a claim upon mens hearts, as for that subtle, something, that quality of air that emanates from old trees, that so wonderfully changes and renews a weary spirit. – Robert Louis Stevenson
