Laotse, Tao Te King 7

Heaven and earth exist for ever.

The reason why their exist so long,

is not that they want to exist;

where there is no want,

to be and not be are one.

Therefore for the sage,

the last becomes the first,

the out becomes the in.

As he is selfless,

all becomes himself.

天长地久，天地所以能长且久者，以其不自生，故能长生。 是以圣人后其身而身先，外其身而身存。非以其无私邪？故能成其私。
