Heaven is eternal - the earth endures.
Why do heaven and earth last forever?
They do not live for themselves only.
This is the secret of their durability.
For this reason the wise sage puts himself last
and so ends up ahead.
He stays a witness to life,
so he endures.
Serve the needs of others,
and all your own needs will be fulfilled.
Through selfless action, fulfillment is attained.
