PURPORT

The history of Vidura is that he was born of a sudra mother, but his seminal father was Vyasadeva; thus he was not less than Vyasadeva in any respect. Since he was born of a great father, who was supposed to be an incarnation of Narayana and who composed all the Vedic literatures, Vidura was also a great personality. He accepted Krsna as his worshipable Lord and followed His instructions wholeheartedly.
