sarve pracetaso nāma dhanurvedasya pāragāḥ //

"Prâchînvarhiṣa begot many children belonging to the Havirdhan clan. He had ten stalwart sons, well versed in archery, who are known as Prachetas, from Savarṇâ, the daughter of Samudra. They all devoted themselves to asceticism, and the trees that they grew to form a small jungle where they could practise their austerities, in process of time developed into a thick forest of vast latitudes which was ultimately burnt down by the fire at the commands of Indra (the God of Rain)."—46-48.
