Ursula K. Le Guin said this quote

The Earth is beautiful, and bright, and kindly, but that is not all. The Earth is also terrible, and dark, and cruel. The rabbit shrieks dying in the green meadows. The mountains clench their great hands full of hidden fire. There are sharks in the sea, and there is cruelty in men's eyes. And where men worship these things and abase themselves before them, there evil breeds; there places are made in the world where darkness gathers, places given over wholly to the Ones whom we call Nameless, the ancient and holy Powers of the Earth before the Light, the powers of the dark, of ruin, of madness.
