He got lots of other weapons from his father Indra by living in Swarg for one year. When he had got the weapons he wanted, and he wanted to come back to Prithvi, Indra asked him to get the training of music and dance too. Arjun laughed at the idea and said - "Why a warrior should need this?" Indra said - "It will be useful during your Agyaatvaas period." 

After finishing that training, when he was coming back, Urvashee Apsaraa got attracted to him and requested him to marry her. Arjun said - "I have always regarded you as my mother, I cannot commit such a sin." At this Urvashee gave him Shaap of being eunuch for his whole life. Later Indra leniently reduced the period for only one year and the year of his choice also, and said to Arjun that "this Shaap will also be useful during your Agyaatvaas period". So when Paandav started their Agyaatvaas period, Arjun became an eunuch and taught music and dance to Raajaa Viraat's daughter Uttaraa. Later he accepted her as Abhimanyu's wife.

When Arjun went to Indra Lok to get Divine weapons from his father Indra, he learned music and dance from his friend Chitrasen, the king of Gandharv. Indra told him that this knowledge will be useful for him during the period of Agyaatvaas. After that he came back to Earth. All Paandav were staying in Dwait Van. Duryodhan heard all about getting his Divine Astra, he got worried. When he expressed his feelings to Dushaasan, Karn and Shakuni, Karn told him that he did not need to worry about it. Rather, if he agrees, he could suggest the way to embarrass them. He told that they should go to their station of cows, which was near to Dwait Van, to inspect them along with their army and women and then show off their glory and valor to them. There was no other way to envy them better than this.

Duryodhan got very happy to hear this, he asked the permission from Dhritraashtra which he got. But later when he told him the real reason to go there, Dhritraashtra was not happy with it. He thought it was risky, but Duryodhan convinced him for it. So all four, Duryodhan, Dushaasan, Karn and Shakuni went there with their army and women and camped there. One day he desired to swim in the lake nearby so he asked his people to check the place. His people told him that a Gandharv was already in it with his women. He ordered his people to ask him to move from that place as the king of Hastinaapur was coming to swim there. The people told him the same, but the Gandharv said - "Tell him that whoever he might be, I am not obliged to obey him." When Duryodhan's people told this to him, he got very angry and sent them to fight with them.

They came and the fight started. But Kaurav army could not face the Gandharv army. When they got weaker, Duryodhan, Dushaasan, Karn and Shakuni also joined them, but still they could not face them. The Gandharv made Duryodhan and many womed captive and took them to his place. The Kaurav army got panic. Some soldiers immediately went to Yudhishthir's camp and told the whole incident. Bheem got very happy to hear this, he said - "We should have done this to them long before. But I am happy that somebody else is doing our work." But Yudhishthir was not happy with Bheem. He said - "Bheem, you should take Arjun, Sahadev and Nakul and go to release them." Bheem said - "No, I wouldn't go to release such a person." Yudhishthir said - " If you will not go, then I will have to go. We are five against hundred, but we are hundred and five against a third man. You should be ashamed of yourself. As a Kshatriya it is your prime duty to protect oppressed. Secondly, you should be ashamed of yourself also that somebody else is doing your work? Then what will happen to your vows?" Now Bheem understood what Yudhishthir was saying.

So he immediately went there and politely requested to release his brother. But the Gandharv army wouldn't let him go. Both parties fought, but Arjun defeated them all. Then their chief came to face Arjun from sky, but Arjun defeated him also, the he came down and revealed himself. Arjun was amazed to see him, he was nobody else but his good friend Chitarsen. They embraced each other and talked about past days for some time. Arjun asked him as why did he capture his brother? Chitrasen said - "To whom you call your brother he did not come there to inspect the cows but he came to insult you, to harass you all. Your father Indra knew it before so he sent me here and asked to pick up a quarrel with him and arrest him. Hearing his arrest, He knew, that Yudhishthir will send you to get him released. Thus Duryodhan to get humiliated and obliged to you." Arjun said - "But now you may release him." Chitrasen said - "No, I will release only to Yudhishthir as he has sent you to get him released him. Then he can do with them whateve he likes" So they all went to him. Yudhishthir aske him to release them so he did. Yudhishthir expressed his gratitude to Chitrasen. Then he looked at Duryodhan and said - "Never do such a stupid thing again. Go now to your kingdom." There was no hatred in his look to Duryodhan it was only pity and gentleness. Duryodhan went away from there lowering his eyes and bent head humiliated greatly.
