Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 18-19
Sanskrit:
दुष्मन्त: स पुनर्भेजे स्ववंशं राज्यकामुक: ।ययातेर्ज्येष्ठपुत्रस्य यदोर्वंशं नरर्षभ ॥ १८ ॥वर्णयामि महापुण्यं सर्वपापहरं नृणाम् ।यदोर्वंशं नर: श्रुत्वा सर्वपापै: प्रमुच्यते ॥ १९ ॥
ITRANS:
duṣmantaḥ sa punar bhejesva-vaṁśaṁ rājya-kāmukaḥyayāter jyeṣṭha-putrasyayador vaṁśaṁ nararṣabha
Translation:
Mahārāja Duṣmanta, desiring to occupy the throne, returned to his original dynasty [the Pūru dynasty], even though he had accepted Maruta as his father. O Mahārāja Parīkṣit, let me now describe the dynasty of Yadu, the eldest son of Mahārāja Yayāti. This description is supremely pious, and it vanquishes the reactions of sinful activities in human society. Simply by hearing this description, one is freed from all sinful reactions.
