Her boon was every time she would call a God they would bless her with a child, born in the normal way. 😳
Hearing this, Kunti said, 'O slayer of foes, a certain Brahamana gave me this formula of invocation as a boon, and, O lord, I have summoned thee only to test its efficacy. For this offence I bow to thee. A woman, whatever be her offence, always deserveth pardon.' Surya (Sun) replied, 'I know that Durvasa hath granted this boon. But cast off thy fears, timid maiden, and grant me thy embraces. Amiable one, my approach cannot be futile; it must bear fruit. Thou hast summoned me, and if it be for nothing, it shall certainly be regarded as thy transgression.'
"Vaisampayana continued, 'Vivaswat thus spoke unto her many things with a view to allay her fears, but, O Bharata, the amiable maiden, from modesty and fear of her relatives, consented not to grant his request. And, O bull of Bharata's race, Arka addressed her again and said, 'O princess, for my sake, it shall not be sinful for thee to grant my wish.' Thus speaking unto the daughter of Kuntibhoja, the illustrious Tapana--the illuminator of the universe--gratified his wish. And of this connection there was immediately born a son known all over the world as Karna accountred with natural armour and with face brightened by ear-rings.
