Sūta said:: The group (of Rākṣasas) called Ālambeya is ferocious and cruel. Similarly, the group Autkaceya (is also cruel). The groups Autkārṣṭeya and Śaiveya are the most excellent groups of Rākṣasas. Similarly, the group named Nairṛta had been procreated by a servant of Tryambaka, the most excellent leader of Gaṇas. The Nairṛtas are Deva-Rākṣasas. They are valorous and richly endowed with heroism. Their leader is one who is endued with Yogic power, well reputed by the name Virūpaka. They are haughty and noble-souled and they form hundreds of groups and armies. Generally these (Nairṛtas) follow Śaṅkara the lord of the Universe.
