As they wait for Arjuna, missing him, the loss of their kingdom and its repercussions are felt more keenly by the Pandavas, . Bheema keeps worrying and expresses his fears to Yudhisthra, 'Maharaja, Arjuna was our life. He has gone away as per your wish. If anything happens to him we are all finished. I cannot imagine the difficulties he is facing now. Let us not wait for twelve years. I will go and bring Arjuna back and call Krishna as well. We should go and kill our opponents now! You can continue your vanavasa later. I do not think it is wrong. If you think it is so, we can perform a yaga to expiate our wrong deeds. Let us act like the khsatriyas we are, it is not right for us to live in a forest!'
The rishi concludes the story and urges Yudhisthira to take courage and try to be happy, teaches him 'Akshahrudaya', in case he is invited to gamble again!
The vachana bharata devotes many pages to this story. I guess it is added as a filler! I had heard the story as a kid. The story is about a very beautiful princess, Damayanti, who hears the qualities of king Nala through a golden swan which speaks, falls deeply in love, chooses him rejecting many devatas in a swayamvara! This obviously is too hard for devatas to accept. A mere human had upstaged them and they scheme to teach Nala a lesson! Not easy as Nala is perfect in everything! He is even the greatest chef in the world. 'Nala paaka' is an epithet used to praise a good recipe and cooking.
But one day this perfect man forgets to wash his feet thoroughly and there is one unwashed spot in his heel. Just what the devatas were waiting for and Shani manages to take advantage of this one imperfect action and Nala's luck changes and bad luck begins. There are many twists and turns to the story but happily all ends well for the couple.
( This grandmothers' story is the reason why we kids would wash our feet thoroughly before entering our homes. Most houses had water taps outside in the garden or we would enter home from the back door and wash our feet in the bath room and only then were we allowed to enter the other rooms! We would also be asked whether we had washed our hands and feet well! It was even more important at a temple. We better wash our feet well before entering the temple or invite Shani kaata. I am not joking. It was pretty serious!)
