The article describes the Upasakamanussavinaya, a Pali text noted with interest by many scholars. Some observations on the issue of upasaka versus monastic practice in Theravada literature. The Upasakamanussavinaya illustrates that Dharmapala was not the first Theravadin to attempt the formalization of lay behavior, since it also has specific rules for the conduct of non-monastics. The companion texts and the discussion of the text in the sermon locate the Upasakamanussavinaya in a repertoire of literature appropriate to the context of public monastic practice.
