ગુણ ઉપર ગુણ કરે, એ વેહેવારાં વટ;

guṇa upara guṇa karē, ē vēhēvārāṁ vaṭa;

Literally: Returning good for good is standard commercial decency;
What it means: Repaying kindness with kindness is a basic obligation, whereas responding with malice is vile.
The English proverb Shah set beside it: Save a rogue from the gallows, he will be the first to cut your throat.Nothing emboldens sin as mercy.Mercy murders but pardons those that kill.
