Srimad Bhagavatam Canto 10, Chapter 51, Text 44

SB 10.51.44

sri-suka uvaca
ity uktas tam pranamyaha
 mucukundo mudanvitah
jñatva narayanam devam
 garga-vakyam anusmaran
Sukadeva Gosvami said: Mucukunda bowed down to the Lord when he heard this. Remembering the words of the sage Garga, he joyfully recognized Krsna to be the Supreme Lord, Narayana. The King then addressed Him as follows.
Although the Lord here appears as four-handed Narayana, we may say that Mucukunda was addressing Sri Krsna. All of this is taking place within the context of krsna-lila, the
pastimes of Lord Krsna. It is well known to Vaisnavas that the four-handed forms of Visnu, or Narayana, are expansions of Sri Krsna. Thus within the pastimes of Lord Krsna there may also appear visnu-lila, the activities of Visnu. Such are the qualities and activities of the Supreme Godhead. Deeds that for us would be extraordinary and even impossible are commonplace, effortless pastimes for the Supreme Personality of Godhead.
Srila Sridhara Svami informs us that Mucukunda was aware of the prediction of the ancient sage Garga that in the twenty-eighth millennium the Supreme Lord would descend. According to Acarya Visvanatha, Garga Muni further informed Mucukunda that he would personally see the Lord. Now it was all happening.
