All life is a struggle in the dark.

Continual dropping wears away a stone.

Those things that are in the light we behold from darkness.

Falling drops will at last wear away stone.

...if one thing frightens people, it is that so much happens, on earth and out in space, the reasons for which seem somehow to escape them, and they fill in the gap by putting it down to the gods.

And part of the soil is called to wash away In storms and streams shave close and gnaw the rocks. Besides, whatever the earth feeds and grows Is restored to earth. And since she surely is The womb of all things and their common grave, Earth must dwindle, you see and take on growth again.

Constant dripping hollows out a stone.
