Dear Lord, here is the great King Nābhi, whose ultimate goal in life is to have a son like You. Your Lordship, his position is like that of a person approaching a very rich man and begging for a little grain. Mahārāja Nābhi is so desirous of having a son that he is worshiping You for a son, although You can offer him any exalted position, including elevation to the heavenly planets or liberation back to Godhead.
