Narada's vision

"And Narada, beholding the fortunate Yudhisthira's prosperity that was born of that sacrifice, became highly gratified. Beholding that vast concourse all the Kshatriyas, the Muni Narada, O king of men, became thoughtful. And, O bull amongst men, the Rishi began to recollect the words he had heard of old in the mansion of Brahma regarding the incarnation on earth of portions of every deity. And knowing, O son of the Kuru race, that that was a concourse (of incarnate) gods, Narada thought in his mind of Hari with eyes like lotus-petals. He knew that that creator himself of every object one, that exalted of all gods--Narayana--who had formerly commanded the celestials, saying,--'Be ye born on earth and slay one another and come back to heaven'--that slayer of all the enemies of the gods, that subjugator of all hostile towns, in order to fulfil his own promise, had been born in the Kshatriya order. And Narada knew that the exalted and holy Narayana, also called Sambhu the lord of the universe, having commanded all the celestials thus, had taken his birth in the race of Yadus and that foremost of all perpetuator of races, having sprung from the line of the Andhaka-Vrishnis on earth was graced with great good fortune and was shining like the moon herself among stars. Narada knew that Hari the grinder of foes, whose strength of arm was ever praised by all the celestials with Indra among them, was then living in the world in human form. Oh, the Self-Create will himself take away (from the earth) this vast concourse of Kshatriyas endued with so much strength. Such was the vision of Narada the omniscient who knew Hari or Narayana to be that Supreme Lord whom everybody worshipped with sacrifice. And Narada, gifted with great intelligence and the foremost of all persons and conversant with morality, thinking of all this, sat at that sacrifice of the wise king Yudhisthira the just with feelings of awe.
