ચતુર હોય તો રીઝવું, હસ્ત રમાડુ છેલ;

catura hōya tō rījhavuṁ, hasta ramāḍu chēla;

Literally: If one is clever, I would please them, playing with hands like a dandy;
What it means: It is worthwhile to engage with and please an intelligent person, but futile to plead with a foolish and malicious one.
