Nick Flynn, "The Ticking Is The Bomb"

Thich Nhat Hahn says it is a mistake to say, "The rain is falling," to say, "The wind is blowing." What is rain if it is not falling? he asks. What is wind if it is not blowing? The falling is the rain, the blowing is the wind. The next day, in the tree, I bring it up. He's talking about impermanence, someone says. It's the same reason we climb trees, someone else offers -- it's that we were once monkeys.

Shakespeare, Hamlet Vii

... in my heart there was a kind of fighting
That would not let me sleep.

Antoine de Saint Exupéry

Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.
