Mbh 3.225.1

“Markandeya continued, ‘When that powerful, high-souled, and mighty being was born, various kinds of fearful phenomena occurred. And the nature of males and females, of heat and cold, and of such other pairs of contraries, was reversed. And the planets, the cardinal points and the firmaments became radiant with light and the earth began to rumble very much. And the Rishis even, seeking the welfare of the world, while they observed all these terrific prodigies on all sides, began with anxious hearts to restore tranquillity in the universe. And those who used to live in that Chitraratha forest said, This very miserable condition of ours hath been brought about by Agni cohabiting with the six wives of the seven Rishis.’ Others again who had seen the goddess assume the disguise of a bird said, ‘This evil hath been brought about by a bird.’ No one ever imagined that Swaha was the authoress of that mischief. But having heard that the (new born) male child was hers, she went to Skanda and gradually revealed to him the fact that she was his mother. And those seven Rishis, when they heard that a son of great power had been born (to them), divorced their six wives with the exception of the adorable Arundhati, because all the dwellers of that forest protested that those six persons had been instrumental in bringing forth the child. Swaha too, O king, said again and again to the seven Rishis, saying, ‘Ye ascetics, this child is mine, your wives are not his mother.’
