"It has the deep firm Root (origin) which establishes Virtue; A Gentleman (junzi) thinks of resolute men when he sees its Root.

"It has the straight Nature (stem) and upstands with it; A Gentleman thinks of upright men when he sees its Nature.

"It has the hollow Heart (interior) which experiences the Way (Dao); A Gentleman thinks of modest men when he sees its Heart.

"It has the clean Chastity (nodes) which sets up will and courage; A Gentleman thinks of spartan men when he sees its Chastity."
