The brothers Jay and Vijay are the two favored gate keepers of Hari. Due to a curse, by the Brahmin Sanaka and his three brothers, Jay and Vijay were born in the species of the demons. One took the birth of Hiranyakashipu and the other was born as Hiranyaksha. The Supreme incarnated Himself as Varaha in order to kill Hiranyaksha, while incarnating as Narasimha to kill Hiranyakashipu. Even though these brothers are killed by Hari Himself, they do not attain liberation as the Brahman's had cursed them to three births and so were reborn as the powerful demons Ravana and Kumbhakarna. Hari took a human incarnation, as Rama, to kill Ravana and Kumbhakarna.
