Alas! While practicing austerity, even within the depths of the water, and while observing all the rules and regulations practiced by saintly persons, I lost the results of my long austerities simply by association with the sexual affairs of fish. Everyone should observe this falldown and learn from it.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
अहो इमं पश्यत मे विनाशं तपस्विनः सच्चरितव्रतस्य । अन्तर्जले वारिचरप्रसङ्गा- त्प्रच्यावितं ब्रह्म चिरं धृतं यत्
aho imaṃ paśyata me vināśaṃ tapasvinaḥ saccaritavratasya | antarjale vāricaraprasaṅgā- tpracyāvitaṃ brahma ciraṃ dhṛtaṃ yat
