dusmantah sa punar bheje
yador vamsam nararsabha
yador vamsam narah srutva
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Maharaja Dusmanta, desiring to occupy the throne, returned to his original dynasty [the Puru dynasty], even though he had accepted Maruta as his father. O Maharaja Pariksit, let me now describe the dynasty of Yadu, the eldest son of Maharaja Yayati. 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.
