"Wisest of men, this is the third time I have tested you. You chose to remain in hell for the sake of your brothers. It is inevitable that kings and rulers must go through hell if only for a while. So it was that for the thirtieth part of a day you too were doomed to suffer the pangs of hell." MB 106 (Mahabharata Retold By C. Rajagopalachari) http://www.krishnapath.org/library/mahabharata-free-download/
