કસણીને હાથે ગરવું સારું, પણ અણકસણીને હાથે જીવવું ખોટું.

kasaṇīnē hāthē garavuṁ sāruṁ, paṇa aṇakasaṇīnē hāthē jīvavuṁ khōṭuṁ.

Literally: It is better to be under the hand of a strict person than to live under the hand of a lenient one.
What it means: Discipline is preferable to the chaos caused by lack of oversight.
