tvam tu mad-dharmam asthaya

 jñana-nistha upeksakah

man-maya-racitam etam

 vijñayopasamam vraja

 

Translation: 

 

You, Daruka, should be firmly situated in devotion to Me, remaining fixed in spiritual knowledge and unattached to material considerations. Understanding these pastimes to be a display of My illusory potency, you should remain peaceful.

 

Purport: 

 

According to Srila Jiva Gosvami, the word tu here emphasizes that Daruka is an eternally liberated associate of Lord Krsna, having descended from Vaikuntha. Therefore, even though others might be bewildered by the Lord’s pastimes, Daruka should remain peaceful and fixed in spiritual knowledge.
