Thunder and rain set in:
The image of DELIVERANCE.
Thus the superior man pardons mistakes
And forgives misdeeds.
A thunderstorm has the effect of clearing
the air; the superior man produces a similar
effect when dealing with mistakes and sins of men
that induce a condition of tension.
Through clarity he brings deliverance.
However, when failings come to light,
he does not dwell on them;
he simply passes over mistakes,
the unintentional transgressions,
just as thunder dies away.
He forgives misdeeds,
the intentional transgressions,
just as water washes everything clean.
