This article examines how Buddhist literatures construct the agency of Buddhist nuns. The first section explores the Vinaya collections of different schools, and examines the differences between the Bhikkhunī-vibha?ga and the Bhikkhu-vibha?ga on how nuns are expected to act. The second section explores material on the faculties (indriyas) in the Pāli Abhidhamma-pi?aka and its commentaries so as to better understand how the abhidhamma analyses of ‘women’s nature’ and ‘men’s nature’ informed conceptions of agency. This article suggests that even though the abhidhamma literature uses such terms as ‘women’s nature’, there is little basis for concluding, as some scholars have done, that Buddhist literature reflects an essentialist view of gender. The fact that the abhidhamma analyses of gender distinguish between ‘male faculties’ and ‘female faculties’ does not appear to make a difference in the agency accorded to nuns: nuns, like monks, are expected to behave in certain ways independent of the fact that they have ‘female faculties’ and thus are inclined toward certain kinds of stereotypically female behaviour.
