Set firm in the Way: None Shall Uproot You

Set firm in the Way: none shall uproot you;
Cherish it well and none shall estrange you;
Your children's children faithful shall serve
Your forebears at the altar of your house.
Cultivate the Way yourself,
and your Virtue will be genuine.
Cultivate it in the home,
and its Virtue will overflow.
Cultivate it in the village,
and the village will endure.
Cultivate it in the realm,
and the realm will flourish.
Cultivate it in the world,
and Virtue will be universal.
Accordingly,
One will be judged by the Man of the Way;
Homes will be viewed through the Home of the Way;
And the Village shall measure the village;
And the Realm, for all realms, shall be standard;
And the World, to this world, shall be heaven.
How do I know 5ybhn world is like this?
By this.
