Possessed of great strength, some amongst them partook of the nature of Yama, some of Rudra, some of Soma, some of Kuvera, some of Varuna, some of Indra, and some of Agni, O scorcher of foes. And some partook of the nature of Vayu, some of Kumara, some of Brahma, O bull of Bharata's race, and some of Vishnu and some of Surya, and some of Varaha.

Capable of assuming any form at will, in fleetness they resembled the very wind. Of inconceivable might and energy, their prowess also was inconceivable.
