Atri said I am called Atri because I purify the world from sin. For, again, thrice studying the Vedas every day, I have made days of may nights. That, again, is no night in which I have not studied the Vedas. Therefore also I am called Atri, O beautiful lady!
अत्रिरुवाच अरात्रिरत्रिः सा रात्रिर्यां नाधीते त्रिरद्य वै। अरात्रिरत्रिरित्येव नाम ते विद्धि शोभने॥
