According to a legend described in Kashi Khand, Sage Kashyap had two wives Kadru and Vinta. Kadru gave birth to hundred snake sons and Vinta gave birth to three sons namely Ulook, Arun and Garuda. Other birds removed Ulook from the designation of Pakshiraj by stated him as ???Nirgun???. This depressed Vinta . So, when she conceived for the second time, she attempted to break the shell of the egg in the premature level only with the wish to see her child. After breaking the premature shell, Arun took birth from it. Arun was perverted being prematurely born. His body above the thighs was fully developed but lower portion was not properly developed. Just after his birth as a prematurely delivered baby, Arun cursed his mother that one day she will become a slave of her sister Kadru. When Vinta requested for the freedom from the curse, Arun told his mother that if she will let her another egg develop properly then she will give birth to a son who will make her free from slavery. With these words, Arun flew to Kashi, established an idol of Lord Surya there and started performing penance. As a result, Suryadev manifested, blessed him with a number of boons and established himself there in form of Arun Aditya.
