Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 31
Sanskrit:
सन्निकर्षोऽत्र मर्त्यानामनादरणकारणम् ।गाङ्गं हित्वा यथान्याम्भस्तत्रत्यो याति शुद्धये ॥ ३१ ॥
ITRANS:
sannikarṣo ’tra martyānāmanādaraṇa-kāraṇamgāṅgaṁ hitvā yathānyāmbhastatratyo yāti śuddhaye
Translation:
In this world familiarity breeds contempt. For example, one who lives on the banks of the Ganges might travel to some other body of water to be purified.
