Indra wanted Arjuna to come to heaven so that he could receive divine weapons, and acquire various skills and knowledge. To bring Arjuna to heaven, Indra sent his divine charioteer Māthali

The Vidyarthi Pancha Laksanam describes five qualities of an ideal student: 1) Kāka-chesta - hard work and persistence 2) Baka-dhyanam-(Crane) – focus and concentration, 3) Śvana (Dog) – alertness, even while resting 4) Alpāhari – moderated eating habits, 5) Grha-tyāgi – detachment from thoughts of home while studying

When Urvaśī cursed Arjuna he told Chitrasena who in turn informed Indra. Indra called Arjuna and told him that the curse will take effect for one year in the 13th year of exile when they would have to stay in disguise

Arjuna respectfully declined Urvaśī's advances, viewing her as a Mother belonging to Kuru Vaṃśa. This made Urvaśī very angry and she pronounced the curse.

Chitrasena taught Arjuna music, dance, playing musical instruments at the advise of Indra. Indra told him that the rare Deva loka music would not be available in Earth and this art would be beneficial to him.

Indra's chariot which was effulgent and which had many weapons such as missiles, mace, lightning-like arrows descended with the roar of huge masses of clouds. The Chariot was drawn by 10,000 fine horses.

Arjuna was led into the beautify city of Indra. Divine chariots were parked in large numbers. He alighted from the chariot and he saw scenes of picturesque beauty. He met a number of rishis and celestials including the Gandharva twins Hāhā and Hūhū.

Arjuna respectfully addressed Urvaśī as Mother because she had been associated with his ancestor Pururavas. He told her that he gazed at her with this thought only.

Apsaras are celestial maidens, a part of nature and belong to an order (time/space) that is different to that of the earthly beings.

The Eight intellectual attributes that Arjuna had, as described by Chitrasena were:
1) Sushrusha - Eagerness to listen and do service to Guru and others; 2) Shravanam - Listening; 3) Grahanam - Absorbing; 4) Dhārana - Remembering; 5) Ūha - Understanding implied meaning constructive reasoning; 6) Apoha - Eliminating irrelevant possibilities / misconception, with reasoning; 7) Arta vignāna - Understanding intended meaning of sentence not just words; 8) Tattva vignāna- Knowledge of reality

When Lomaśa Rishi arrived in heaven, he was surprised to find Arjuna seated on the same throne beside Indra. Such a privilege was reserved only for the greatest of divine beings. Seeing a human prince receiving equal honour from Indra made the sage wonder about Arjuna's penance and merits.

Indra mentions to Lomaśa Rishi that a type of Asurās are in Pātala regions. They are called Nivātakavachas. They could be defeated only by either Bhagavān Hari or Arjuna. Indra said that Arjuna will return back to earth after defeating the Nivātakavachas and wanted Lomaśa Rishi to convey this to Yudhiṣṭhira.

Yudhiṣṭhira says to Bhīma on subtleties of Dharma that:-
1) The dharma of self does not depend on action of other.
2) When promise is given with awareness, following it is a matter of character 
3) Prudence presupposes Justice - Strategically Desa Kala Paristhithi is more important when making decisions 4) Dharma is not about mere legal correctness. It is about your truthfulness and integrity of your value system and character 5) Have faith and the effectiveness of Dharma. Don't Expect results and make Dharma a transaction.
