Note 242 — Chapter LXXIV · INDRA COMES AND EULOGISES KRISHNA.
Manmatha Nath Dutt translation
Kunti, while a maid, obtained a boon from the Rishi Durvasa that whomever she would wish to have as her consort, he would at once come to her. To make an experiment she invoked the sun and Karna is the issue of her union with him. The account of his birth is described in one hundred and eleventh chapter of Adi Parva in the Mahabharata.
