Translation: 
“[When he was being blessed by the Supreme Personality of Godhead, Dhruva Mahārāja said:] ‘O my Lord, because I was seeking an opulent material position, I was performing severe types of penance and austerity. Now I have gotten You, who are very difficult for the great demigods, saintly persons and kings to attain. I was searching after a piece of glass, but instead I have found a most valuable jewel. Therefore I am so satisfied that I do not wish to ask any benediction from You.’
