કાયા ઘટમાં કાંકરા, જે કદિ પેસી જાય; નીકળતાં નીકળે નહીં, કરીએ કોટી ઉપાય.

kāyā ghaṭamāṁ kāṁkarā, jē kadi pēsī jāya; nīkaḷatāṁ nīkaḷē nahīṁ, karīē kōṭī upāya.

Literally: Pebbles in the vessel of the body, if they ever enter; do not come out even if one tries ten million remedies;
What it means: Deep-seated bad habits, vices, or chronic diseases are extremely difficult to get rid of once they take root.
