હાથ હથોડી લે કર, સદ્ગુરુ મિલે સુનાર;

hātha hathōḍī lē kara, sadguru milē sunāra;

Literally: Taking a hammer in hand, the true guru meets like a goldsmith.
What it means: Strict discipline from a wise teacher shapes and refines a student.
The English proverb Shah set beside it: Spare the rod and spoil the child,Lay on a rod and you will bring on a good scholar.A whip for a fool and a rod for a school is always good in season.Foolish pity spoils the city.
