Hiraṇyapura was a wondrous aerial city capable of changing its position and evading attacks. Arjuna had to contend not only with powerful opponents but also with the city's extraordinary mobility.

Brahmā granted the Nivātakavacas a formidable boon that made them incapable of being killed by Devas and other asuras. It made them arrogant in their strength.

Arjuna undertook intense penance to please the gods and obtain celestial weapons. These weapons were intended to strengthen the Pāṇḍavas for the challenges they would face in the future.

Lord Śiva appeared as a powerful hunter, accompanied by Goddess Parvati and his attendants. Arjuna initially did not recognise the hunter as Lord Śiva.

A wild boar appeared during Arjuna’s penance. Both Arjuna and the hunter released arrows at it, and a dispute arose over who had struck it first. This led to their fierce encounter.

Pleased with Arjuna’s courage, determination and devotion, Lord Śiva revealed his divine form and granted him the powerful Pāśupatāstra. This weapon was to be used with great care and only under appropriate circumstances.

Mātali was the divine charioteer of Indra. He drove the celestial chariot for Arjuna during the battle against the Nivātakavacas.

Seeing Arjuna in distress, Mātali called out, "O Arjuna, Arjuna! don't get afraid; send that weapon, the thunder-bolt." Arjuna then discharged Indra's mighty Vajra weapon, destroying the demons and their illusions.

Pulomā , the daughter of a Daitya, and Kālakā, a mighty Asura woman, performed intense penance for 1,000 divine years. Pleased with their austerities, Lord Brahmā appeared before them and granted boons.

Lord Śiva instructed Arjuna to use the powerful Pāśupatāstram with great restraint and not against weaker opponents or ordinary humans.

Amarāvathi is the magnificent city that serves as the capital of Indralokam, where Indra resides.

Devadattam is Arjuna's divine conch, gifted by Indra.
