The great sage Maitreya Muni said to Vidura: The royal dynasty of King Pūru is worthy to serve the pure devotees because all the descendants of that family are devoted to the Personality of Godhead. You are also born in that family, and it is wonderful that because of your attempt the transcendental pastimes of the Lord are becoming newer and newer at every moment.
