ARUNAArun, the charioteer of the lamp of the world (i.e. the sun) and brother of Garuda, the king of the birds became a cripple on account of his past actions. (Dhanasari Trilochan, p. 695) Aruna was the son of Kashyapa (Brahma\’s son) by his wife Vinata. Kashyapa had two wives: Vinata and Kadru. Having been pleased by their services, he granted them boons. Kadru was to be blessed with one thousand naga (serpent) sons and Vinata with two powerful sons. Kadru laid one thousand eggs and Vinata two.
After five hundred years, Kadru had one thousand sons. Vinata\’s eggs were not mature as yet, but she became so much impatient that she broke open one of her eggs and a half-developed child, Aruna, came out. After another five hundred years, the other egg of Vinata, which became fully developed, hatched itself and her second son Garuda was bom. On his pre-mature birth, Aruna cursed his mother to live as slave of Kadru till the birth of her second son.
After pronouncing the curse, Aruna rose to the sky and on the advice of Brahma, became the charioteer of sun-god, so that by standing before the god, the intensity of his heat may be reduced. It is said that Aruna broke the legs of some birds in one of his previous births, therefore in pursuance of the law of Kanna, he became a cripple as the brotner of Garuda. One cannot escape the punishment of previous actions.
