Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 23
Sanskrit:
न ह्यम्मयानि तीर्थानि न देवाश्चेतनोज्झिता: ।ते पुनन्त्युरुकालेन यूयं दर्शनमात्रत: ॥ २३ ॥
ITRANS:
na hy am-mayāni tīrthānina devāś cetanojjhitāḥte punanty uru-kālenayūyaṁ darśana-mātrataḥ
Translation:
Mere bodies of water do not constitute holy places, nor are lifeless statues of the demigods actual worshipable deities. Because external vision fails to appreciate the higher essence of the holy rivers and the demigods, these purify only after a considerable time. But devotees like you purify immediately, just by being seen.
