[[From the ruler down to the ordinary people, all must regard the cultivation of the self as the root.
It is impossible for the root to be in disarray but the branches to be well ordered.
You should never trivialize what is important or give importance to what is trivial.
This is called knowing the root. This is called extending your knowledge.->commentary]]Knowledge are like the roots of a tree,

By not making the important unimportant,
And by not making the unimportant important.
