Heaven and earth

Heaven and earth do not act from (the impulse of) any wish to be

benevolent; they deal with all things as the dogs of grass are dealt

with. The sages do not act from (any wish to be) benevolent; they

deal with the people as the dogs of grass are dealt with.

May not the space between heaven and earth be compared to a

bellows?

'Tis emptied, yet it loses not its power;

'Tis moved again, and sends forth air the more.

Much speech to swift exhaustion lead we see;

Your inner being guard, and keep it free.
