SB 10.51.13
sri-rajovaca
ko nama sa puman brahman
kasya kim-virya eva ca
kasmad guham gatah sisye
kim-tejo yavanardanah
Translation:
King Pariksit said: Who was that person, O brahmana? To which family did he belong, and what were his powers? Why did that destroyer of the barbarian lie down to sleep in the cave, and whose son was he?
