have you read the Mahabharata? A major portion of the same is sub-plots - stories narrated by the well-wishers visiting the Pandavas in exile - like the story of Nala and Damayanti to lighten their burden during stay in the forests and make them understand that even good people face adversities. Read it as a story - I do not claim that it is some divine revealation, etc. Don't jump to conclusions.
