4.2.1

parāśara uvāca:
yāvac ca brahmalokāt kakudmī raivato nābhyeti tāvat puṇyajanasaṃjñā rākṣasās tām asya purīṃ kuśasthalīṃ jaghnuḥ ||

PARÁŚARA.--Whilst Kakudmin, surnamed Raivata, was absent on his visit to the region of Brahmá, the evil spirits or Rákshasas named Puńyajanas destroyed his capital Kuśasthalí. His hundred brothers, through dread of these foes, fled in different directions; and the Kshatriyas, their descendants, settled in many countries.
