This article compares two versions of a story about a Tibetan Buddhist monk, Sgra tshad pa Rin chen rnam rgyal, who engages in sexual intercourse with a laywoman. The authors of these two narratives, dating from the fifteenth and nineteenth centuries, each provide a different rationale for the monk’s behavior. In the earlier telling, Rin chen rnam rgyal is said to have “eased the suffering” of a “lust-crazed” woman, conducting himself virtuously, as a bodhisattva. In the later telling, the monk (...) is forcibly seduced by his patron and he adheres to a provision found in the Mūlasarvāstivāda Vinaya, which specifies that the usual punishment intended for a Vinaya transgression of sexual intercourse—loss of communion from the order—may be commuted if the act has not been concealed from others. This article focuses on the transformation of the story and proposes that its changes contribute to the author’s wider commentary on strict Vinaya observance as an element of Buddhist monastic exemplarity.
