Vaivahika Parva is the thirteenth upa parva in the first maha parva, named as Adi parva, in the epic Mahabharata. Vyshampayana had narrated the historical events to Janamejaya, on his queries:
What was the opinion of King Drupada regarding his son in laws?
King Drupada was very happy to know about his sons in laws. He wished to give away his daughter in marriage to Pandavas. When Drupada learnt that the successful people of swayamvara were the Pandavas, he felt extremely happy. He decided to conduct a feast to the guests of swayamvara with the Pandavas and sent through his priest, an invition to Pandavas for attending the feast.
