She belonged to an eminent brahmin family of Sāvatthi and, in her twentieth year, renounced the world under Mahāpajāpatī Gotamī.

One day, as she meditated after her return from the almsround, the Buddha appeared before her in a ray of glory and exhorted her in a verse. Not long after she became an Arahant.

In the past, she had seen Vipassī Buddha walking along the street and, gladdened by the sight, had rushed out and thrown herself at his feet (Thig.vs.2; ThigA.8 f).

She is evidently identical with Saṅkamanattā of the Apadāna. Ap.ii.514.
