vipracittiḥ saiṃhikeyān siṃhikāyām ajījanat //

The Paulomas and the Kâlikêyas, *i.e.*, the demon progeny of Pulomâ and Kâlikâ, after being made invulnerable even against the Devas, began to live in Hiraṇyapura. Lord Viṣṇu killed the Paulomas and Kâlikêyas, who had become most haughty after they were made invulnerable by Brahmâ. Only Viprachit survived, and he produced another race of thirteen demons, known as Saihiṁkêya from the womb of Siṁhikâ the sister of Hiraṇyakaśipu.—24-25. Note.—The Paulomas and the Kâlikêyas were only made invulnerable by Brahmâ, and only the minor Gods could not kill them, but Lord Viṣṇu is the Supreme God.
