This article examines origins of Onsenji, a temple at Arima hot springs, together with a set of closely related tales of other sites of curative bathing where religious exemplars encounter Buddhist deities of healing, to explore narrative and doctrinal patterns of engi genre. It suggests how a common literary trope, of deities who appear as lepers to test compassion and perception of their followers, serves institutional priorities of particular local sites and how contents of these tales articulate Buddhist claims about pollution and purity, ignorance and insight, and sickness and salvation. It argues that soteriology of these stories, in which mental defilements are shown to be origin and engine of all human suffering, express in narrative form meaning of term engi as a Buddhist technical term for theory of dependent origination.KEYWORDS: Onsen engi-Gyoki-Yakushi-lepers-bathhouses-healing(ProQuest: ... denotes non-US-ASCII text omitted.)ON THE SEVENTH day of fourth month of 1452, Zuikei Shuho ...

Zuikei's description of having listened to history of temple while viewing a painting also reminds us that textual and visual modes were often coarticulated and that engi should also be understood as performative: they belonged to repertoire of picture recitation (etoki . …
