How lovely trees are. The human species grew up in and around them. We have a natural affinity for trees. … We human beings don’t look very much like a tree. We certainly view the world differently than a tree does. But down deep, at the molecular heart of life we’re essentially identical to trees. ~ Carl Sagan (Cosmos)
When a man plants a tree, he plants himself. Every root is an anchor, over which he rests with grateful interest, and becomes sufficiently calm to feel the joy of living. ~ John Muir (Steep Trails)
A tree is a self: it is unseen shaping more than it is leaves or bark, roots or cellulose or fruit. … We can not point to anything physical and say, “There is the self!” This holds for the tree’s activity as well as for the human’s. What it means is that we must address trees. We must address all things, confronting them in the awareness that we are in the presence of numinous mystery. Who shapes the tree? Who shapes my thoughts? We are in the mystery of the self. ~ Brian Swimme (The Universe Is a Green Dragon: A Cosmic Creation Story)
