under his control. Next, he turned his eyes towards Svargaloka. Even the mighty Indra could not withstand the assault of this son of Vishnu, and had to flee the heavens. Narakasura had become the overlord of both the heavens and earth. Addicted to power, he stole the earrings of Aditi, the heavenly mother goddess, and usurped some of her territories, while also kidnapping 16000 women. All the devas, led by Indra, went to Vishnu to ask him to deliver them from Narakasura. Vishnu promised them that he would attend to this matter, when he would be incarnated as Krishna. Death As promised to the earth goddess, Naraka was allowed to enjoy a long reign. At last, Vishnu was born as Krishna. Aditi, who was a relative of Krishna's wife Satyabhama (believed to be an avatar of Bhudevi - Narakasura's mother), approached Satyabhama for help. When Satyabhama heard of the Narakasura's ill-treatment of women and his behaviour with Aditi, she was enraged. Satyabhama approached Krishna for permission to wage a war against Narakasura. As promised to the devas and Aditi, Krishna attacked the great fortress of Narakasura, riding his mount Garuda with wife Satyabhama. Krishna used the Narayanastra and the Agneyastra against the army of Narakasura. The battle was furiously fought. Narakasura possessed 11 Akshauhinis that he unleashed on Krishna. However, the deity slew them all with little effort. Krishna also killed Mura, Narakasura's general. Thus, Krishna is called 'Murāri' (the killer of Mura). Narakasura used several divine weapons against Krishna, but the latter easily countered all those weapons. Narakasura employed the Brahmastra against Krishna, but Krishna neutralised it with his own Brahmastra. Narakasura used the Agneyastra against Krishna, but Krishna nullified it with the Varunastra. Narakasura hurled the Nagapasha against Krishna, but Krishna negated it with the Garudastra. In desperation, Narakasura launched the Vaishnavastra on Krishna, but Krishna met it with another Vaishnavastra. At last, when Narakasura tried to kill Krishna with a trident, Krishna pretended to swoon, because of a boon that Narakasura could be killed only by the one who gave birth to him. Outraged, Satyabhama attacked Narakasura and beheaded him with Krishna's Sudarshana Chakra (discus). In popular culture It is believed in some traditions that before Narakasura's death, he requested a boon from Satyabhama (incarnation of Bhudevi), that everyone should celebrate his death with colourful lights. Thus, this day is celebrated as 'Naraka Chaturdashi' - the beginning
