SB 6.5.34
etasmin kala utpatan
bahun pasyan prajapatih
purvavan narada-krtam
putra-nasam upasrnot
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
At this time, Prajapati Daksa observed many inauspicious signs, and he heard from various sources that his second group of sons, the Savalasvas, had followed the path of their elder brothers in accordance with the instructions of Narada.
