1. Sumedhā Therī.– She was the daughter of King Koñca of Mantāvatī. When she came of age, her parents let Anikadatta, king of Vāranavatī, see her. However, she had frequent association with nuns, and cut off her hair by herself, and then, concentrating her attention on the idea of the “foul,” she attained the first jhāna. When her parents entered her room with Anikadatta, she converted them all, and obtained permission to join the Order. Shortly afterwards she attained Arahantship.
In the time of Koṇāgamana Buddha she and her friends (afterwards Dhanañjānī and Khemā), clansmen’s daughters, agreed together to have a large monastery built, and this they made over to the Buddha and the Order. In the time of Kassapa Buddha she belonged to a very rich family and was a friend of the seven daughters of Kikī. Thig.vs.448‑522; ThigA.272 f; Ap.ii.512 f; cf. 545 (vs. 24).
