Trees are the earth’s endless effort to speak to the listening heaven.                —Rabindranath Tagore

The tree which moves some to tears of joy is in the eyes of others only a green thing that stands in the way. Some see Nature all ridicule and deformity, and some scarce see Nature at all. But to the eyes of the man of imagination, Nature is Imagination itself.

                                                                                       —William Blake

Sensing us, the trees tremble in their sleep, / The living leaves recoil before our fires, / Baring to us war-charred and broken branches, / And seeing theirs, we for our own destruction weep.

                                                                                     —Kathleen Raine

God is the experience of looking at a tree and saying, “Ah!”

                                                                                  —Joseph Campbell

Keep a green tree in your heart and perhaps a singing bird will come.               —Chinese proverb

I like trees because they seem more resigned to the way they have to live than other things do. —Willa Cather

If trees could scream, would we be so cavalier about cutting them down? We might, if they screamed all the time, for no good reason.

                                                                                          —Jack Handey

I think that I shall never see / A billboard lovely as a tree. / Perhaps, unless the billboards fall, / I’ll never see a tree at all.

                                                                                            —Ogden Nash

Because they are primeval, because they outlive us, because they are fixed, trees seem to emanate a sense of permanence. And though rooted in earth, they seem to touch the sky. For these reasons it is natural to feel we might learn wisdom from them, to haunt about them with the idea that if we could only read their silent riddle rightly we should learn some secret vital to our own lives; or even, more specifically, some secret vital to our real, our lasting and spiritual existence.    —Kim Taplin

There is always music amongst the trees in the garden, but our hearts must be very quiet to hear it.      —Minnie Aumonier

What did the tree learn from the earth to be able to talk with the sky?             —Pablo Neruda
