Vidura was born from the body of Veda-vyasa and was not less than he. Thus he accepted the lotus feet of Krsna wholeheartedly and was attached to His devotees.
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.
