Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 23
Sanskrit:
जलौघैर्निरभिद्यन्त सेतवो वर्षतीश्वरे ।पाषण्डिनामसद्वादैर्वेदमार्गा: कलौ यथा ॥ २३ ॥
ITRANS:
jalaughair nirabhidyantasetavo varṣatīśvarepāṣaṇḍinām asad-vādairveda-mārgāḥ kalau yathā
Translation:
When Indra sent forth his rains, the floodwaters broke through the irrigation dikes in the agricultural fields, just as in the Kali-yuga the atheists’ false theories break down the boundaries of Vedic injunctions.
