Jaya-Vijaya

In Hinduism, Jaya and Vijaya are the two ''dvarapalakas'' (gatekeepers) of Vaikuntha, the abode of the god Vishnu. Due to a curse by the four Kumaras, they were forced to undergo multiple births as mortals who would be subsequently killed by various avatars of Vishnu. They were incarnated as Hiranyakashipu and Hiranyaksha in the Satya Yuga, Ravana and Kumbhakarna in the Treta Yuga, and finally Shishupala and Dantavakra in the Dvapara Yuga. Provided by Wikipedia
