The daughter of Atri, who was married to Angiras. Angiras always spoke harshly to Aatreyi, who complained about this to her father. Atri told her that her husband was a son of Agni and hence the anger. He advised that she should bathe him. She took the advise and transformed into a river to placate him. As per Brahmandapurana, this river is called Parushni.
