Tao Te Ching: Chapter 5
Heaven and earth are uncompromising
and burn everything as a sacrifice.The way of the sage is uncompromising and lets it all burn.
The space between heaven and earth works like a bellows;
the more it moves the more it fans the fire,
and it cannot run out of air.All this talk about this or that will only end up as ashes.
It's better to stay in-between.
