sa tvam katham mama vibho ’ksi-pathah paratma

Translation:
O almighty one, how is it that my eyes see You here before me? You are the Supreme Soul, whom the greatest masters of mystic yoga can meditate upon within their pure hearts only by employing the spiritual eye of the Vedas. Then how, O transcendental Lord, are You directly visible to me, since my intelligence has been blinded by the severe tribulations of material life? Only one who has finished his material entanglement in this world should be able to see You.
Purport:
Even in the body of a lizard, King Nrga could remember his previous life. And now that he had the opportunity to see the Lord, he could understand that he had received special mercy from the Personality of Godhead.
