About Therīgāthā

The Therigatha (Therīgāthā), often translated as Verses of the Elder Nuns, is a Buddhist text, a collection of short poems of early enlightened women who were elder nuns. The poems date from a three hundred year period, with some dated as early as the late 6th century BCE. According to Thanissaro Bhikkhu, the Therigatha is the "earliest extant text depicting women’s spiritual experiences." in Theravada Buddhism.
Dhammananda Bhikkhuni, the first modern Thai woman to receive full ordination as a Theravada bhikkhuni and Abbess of Songdhammakalyani Monastery, the only temple in Thailand where there are bhikkhunis.

Fully ordained Buddhist nuns – people & concepts

A bhikkhunī or bhikṣuṇī is a fully ordained female monastic in Buddhism. Male monastics are called bhikkhus. Both bhikkhunis and bhikkhus live by the Vinaya, a set of rules. Until recently, the lineages of female monastics only remained in Mahayana Buddhism and thus are prevalent in countries such as China, Korea, Taiwan and Vietnam but a few women have taken the full monastic vows in the Theravada and Vajrayana schools over the last decade. .
