SB 9.20.31
jitva purasura devan
ye rasaukamsi bhejire
deva-striyo rasam nitah
pranibhih punar aharat
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Formerly, after conquering the demigods, all the demons had taken shelter in the lower planetary system known as Rasatala and had brought all the wives and daughters of the demigods there also. Maharaja Bharata, however, rescued all those women, along with their associates, from the clutches of the demons, and he returned them to the demigods.
