An arahant Therī. She was born in a family of Vesāli and was so called because of her sturdy build. She married and became a devoted wife, accepting the Buddha's teaching, after hearing him preach at Vesāli. Later she heard Pajāpatī Gotamī and wished to leave the world, but her husband refused his permission. One day, while cooking, she developed the thought of impermanence and became an Anāgāmī. When her husband realised this, he took her to Pajāpatī, who ordained her.
In the past she had entertained Konāgamana Buddha and built for him an arbour with draped ceiling and sanded floor.
In the time of Kassapa Buddha she was a nun. Thig.1; ThigA., p.5.
