Story of Vidurani, a great devotee of Lord Krishna
Mahabharata is home to one character that could make the ideal king. But fate decided that he would be born to a maid. Vidura was the wisest of all, and his foresight saved Pandavas.
Vidura was halfbrother to Pandu (Dhritarashtra) and Pandu. He was the child of a maid-servant. According to some, Yama or Dharma Raja was his incarnation. Mandavya cursed him with punishments that far exceed the sin.
Both queens were heiresses to King Vichitravirya Of Hastinapur. The latter died in childlessness. Satyavati Vichitravirya was eager to ensure the continuation of the royal line. She called her second son Vyasa to summon his mystical powers to grant motherhood and the two queens. Vyasa, a sage ascetic hermit, came to the palace untidy. Ambika was shocked to see him and closed her eyes. Ambalika, however, became pale. Therefore, their children were born blind and albino.
Satyavati asked Vyasa for permission to go back to Ambika’s bed so that she could have children. Instead, she put her maidservant on her bed. The dutiful maidservant didn't seem afraid. So her son was not like his half-siblings. Vidura was thus born as the brother of Dhritarashtra Pandu.
Bhishma who he called father, raised Vidura with his half brothers. Vidura, whose parents were not of royal blood (sage Vyasa had divine but not royal lineage), was not eligible to become a king. He served as chancellor to his brothers.
