12.36

不應作而作　應作而不作
悔惱火所燒　後世墮惡道
若人罪能悔　悔已莫復憂
如是心安樂　不應常念著
若有二種悔　若應作不作
不應作而作　是則愚人相
不以心悔故　不作而能作
諸惡事已作　不能令不作

"Doing what should not be done,
and not doing what should be done,
one is burned by the fire of regret and vexation,
and in future lives falls into the evil destinies.
If a person is able to repent of sins,
having repented, let him sorrow no more.
In this way the mind is peaceful and joyful;
one should not constantly brood upon it.
If there are the two kinds of regret—
either that what should be done was not done,
or that what should not be done was done—
these are the marks of a foolish person.
It is not through a regretful mind
that what was not done can be done;
once all evil deeds have been done,
one cannot make them undone."
