Two useful verses.

Hostis non ledit, nisi cum temptatus obedit.

Est leo si sedit, si stat quasi musca recedit. 20

The tempter is a lion, if we sit still;

but if we resist, he is but a fly.

A fainthearted captain loses his castle,

and is a traitor. But if he resist, the enemy will not tarry.

Every man is captain of his own soul.
[Fol. 84b.]
