 Kaalika puraana, Durgaa sapthashati and other vedic literature have mentioned about Goddess Kanaka Durga on the Indrakeelaadri and have described the deity as Swayambhu, (self-manifested) in Triteeya kalpa.According to a legend, the now verdant Vijayawada was once a rocky region strewn with hills that obstructed the flow of River Krishna.The land was thus rendered unfit for habitation or cultivation.
