Sri Badarayani said: O King, one day Samba, Pradyumna, Caru, Bhanu, Gada and other young boys of the Yadu dynasty went to a small forest to play.
Purport:
Srila Sridhara Svami states that the story of King Nrga, narrated in this chapter, is meant to give sober instructions to all proud kings. Through this incident Lord Krsna also gave serious lessons to the members of His own family who had become proud of their opulences.
