Yudhishthara went to the first of Kamyaka on the banks of Saraswati.
There he told Arjun that he needs to go to Indra to acquire the weapons. He told him to go north to the mountain to Indra’s abode and traverse a path north and stop anyone from passing him.
When Arjun reached Indra’s abode in the Himalayas, Indra appeared in front of him as an ascetic and promised to grant him a boon. Arjun asked for knowledge of weapons and Indra said when Arjun had met Shiva, Indra will grant him the knowledge.
Arjun reaches a Himalaya peak and performs austerities there and Shiva shows himself disguised as a hunter. Both of them fight and Arjun loses but Shiv is pleased with his valor and shows him his true form and grants him a boon.
Arjun asks for the pashupata also known as brahmashira weapon which can destroy anything in three worlds and Shiva grants him that.
Yama, Varuna, Kuber and Indra then appear in front of him.
Yama gives him the staff, Varuna the noose and Kuber invisibility. Then Indra grants him his chariot to ascend to heavens.
This is the end of this section.
This is the section about the visit to Indra’s abode.
Arjun lives here for five years and gets the Vajra as well as training on weapons. He also learns singing and dancing here.
One day the rishi Lomasa visits heaven and is surprised to see Arjun seated in Indra’s throne because Arjun is just a Kshatriya.
Indra tells him that ancient Nara and Narayana are Dhananjaya and Hrishikesh. So Nara and Narayana are Arjun and Krishna. Nara and Narayana are further fifth avatars of Vishnu, twins born to Dharma whose chief abode is in Dwarika.
Indra tells him that the powerful asurs Nivatakavachas are harassing the gods and only Arjun and Krishna together can kill them and that’s one of their purposes on earth and why they are born.
Further, he tells Lomasha to visit Yudhishthara and tell him that Arjun will return soon and to protect Yudhishthara.
Now there’s a slight break where Janmajeya asks about Dhritarashtra and is told that he is repenting his decision. Then there’s an interesting question about what the Pandavas ate and whether they cultivated their food or gathered it. Dwaipayana answers that they hunted deer and ate what they gathered.
Janmajeya then asks what did the Pandavas do for five years without Arjun and Dwaipayana recounts that they were extremely sad and Bhima again urged Yudhishthara to recall Arjun and go to battle and blamed Yudhishthara for his gambling vice.
Yudhishthara pacifies him and at that moment a Rishi Brihadashva arrives whom Yudhishthara asks is there any man more unfortunate than him?
This starts the story of Nala.
