PURPORT

Krsna has many potencies: parasya saktir vividhaiva sruyate (Svetasvatara Upanisad 6.8). The description of Aghasura was disclosed after one year. Some act of Krsna's potency must have been involved. Therefore Maharaja Pariksit was very curious to know about this, and he requested Sukadeva Gosvami to explain it.
