SB 5.7.2

tasyam u ha va atmajan kartsnyenanurupan atmanah pañca janayam asa bhutadir iva bhuta-suksmani sumatim rastrabhrtam sudarsanam avaranam dhumraketum iti.
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Just as the false ego creates the subtle sense objects, Maharaja Bharata created five sons in the womb of Pañcajani, his wife. These sons were named Sumati, Rastrabhrta, Sudarsana, Avarana and Dhumraketu.
