Srimad Bhagvata Mahapurana: Book 3: Chapter 19: Verses 16-31
Hit in this manner by the demon, O Vidura, the Lord, who appeared as the First Boar, did not feel the least quaking in any part of His body, any more than an elephant would when struck with awreath of flowers. He now employed many a conjuring trick against Sri Hari, the Lord of Yogamaya (the source of all Mayas), at the sight of which the people were filled with alarm and thought the dissolution of the universe was near. Fierce winds began to blow, which spread darkness occasioned by dust. And stones came in volleys from every quarter as if thrown from slings. The luminaries in the heaven disappeared due to the sky being overcast with masses of clouds, which were accompanied by lightning and thunder, and frequently rained pus, hair, blood, faeces, urine and bones. Mountains discharging weapons of various kinds appeared, O sinless Vidura, as also naked demonesses armed with tridents, their hair hanging loose. Most cruel and savage slogans where uttered by hosts of Yaksas and Raksasas who were all of a ruffian type and either marched on foot or rode on horses or elephants or in chariots. The Lord, who represented all the sacrifices in His person, now discharged His beloved discus, Sudarsana, which was capable of dispersing the Mayas (magical forces) displayed by the demon. That very moment, all of a sudden, a shudder ran through the heart of Diti (Hiranyaksa's mother) as she recalled the words of her lord (the sage Kasyapa); and blood flowed from her breasts. When he saw his magic forces dispelled, he went into the presence of Lord Kesava once more and, full of rage, encompassed Him within his arms (in order to crush Him; but to his great amazement and chagrin) he found the Lord standing outside the circle of his arms. As he (now) began to strike the Lord with his fists, which were harder than adamant, Lord Adhoksaja (who is beyond sense-perception) slapped him in the root of his ear, even as Indra (the lord of the Maruts or gods of winds) hit the demon Vrtra (son of Twasta, the architect of the gods). Though struck indifferently by the Lord, the conqueror of all, the demon's body began to wheel, the eye-balls bulged out of their sockets, and he fell down dead like a gigantic tree uprooted by the wind, his arms, legs and hair on the head broken and scattered. Brahma and others, who had now arrived (on the spot) saw the demon with fearful tusks lying on the ground, biting his lips, the glow on his face yet unfaded, and admiringly said, "Oh, who could meet such a (blessed) death! Struck by a fore-foot of the Lord-whom Yogis meditate upon in seclusion through Yoga in the form of abstract meditation, seeking freedom from their limitation, which is unreal-and gazing on His countenance, this crest-jewel of Diti's sons has shuffled off his mortal coil These two demons (Hiranyakasipu and Hiranyaksa) are no other than the Lord's own attendants, who have attained to this accursed state (have been born as demons) through a curse (pronounced by the sage Sanaka and his three brothers). After going through some more births they will return to their (divine) Abode." The gods addressed the Lord : Hail, hail to You, the source of all sacrifices; who have assumed a form consisting of pure Sattva (goodness) for the purpose of maintaining this world. Fortunately for us this demon, who was a torment to the worlds, has been slain (by You) and we too, O Lord, are at ease (now) through devotion to Your feet. Maitreya continued : Having thus killed Hiranyaksa of irresistible prowess, Sri Hari, who had appeared in the form of the First Boar, retired to His own (divine) realm, which is the abode of uninterrupted joy; while Brahma (who has his seat on a lotus) and others extolled him.
