Vidura was overwhelmed by the ecstasy of love when he understood that Lord Krsna, the Supreme Personality of Godhead, thought of him at the last moment. Although he thought of himself as insignificant, he was remembered by the Lord, by His causeless mercy. Vidura accepted this as a great favor, and thus he cried. This crying is the last word in the progressive path of devotional service. One who can cry for the Lord in love is certainly successful in the line of devotional service.
