The second encounter is with Arjuna who wonders why Lord Rama needed the help of monkeys to build a bridge. Hanuman appears in the form of a normal monkey and challenges Arjuna that his bridge would collapse even under the weight of one person. Arjuna says that if that happens he will jump into a fire.
When Arjuna builds a bridge with just his arrows and Hanuman steps on it, the bridge breaks. When Arjuna tries to jump into fire, Lord Krishna appears and repairs the bridge which does not break again.
Hanuman then reveals his form and tells Arjuna that he will support him in the Kurukshetra war. Hanuman fights alongside Arjuna till the end.
Hanuman has a crucial part to play!
We are all familiar with Lord Hanuman’s extremely important role in Ramayana. But only a few of us know that Lord Hanuman also appears in the epic Mahabharata, that too twice. It is a well-known fact that Lord Hanuman is one of the ‘Chiranjeevis’. Chiranjeevis are the people who are supposed to be immortals. Hanuman, being one of the Chiranjeevis has been granted with the boon to live forever.
When Hanuman met Arjuna and Bheema
So, we find Lord Hanuman being mentioned in Mahabharata. Lord Hanuman is also considered the brother of Bhima as they have the same father, Vayu. Therefore the first mention of Lord Hanuman in Mahabharata comes when He meets Bhima during the Pandavas exile and the second time when Lord Hanuman protected the chariot of Arjuna throughout the battle of Kurukshetra by residing in Arjuna’s flag.
