Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 31
Sanskrit:
न ह्यम्मयानि तीर्थानि न देवा मृच्छिलामया: ।ते पुनन्त्युरुकालेन दर्शनादेव साधव: ॥ ३१ ॥
ITRANS:
na hy am-mayāni tīrthānina devā mṛc-chilā-mayāḥte punanty uru-kālenadarśanād eva sādhavaḥ
Translation:
No one can deny that there are holy places with sacred rivers, or that the demigods appear in deity forms made of earth and stone. But these purify the soul only after a long time, whereas saintly persons purify just by being seen.
