The purpose of this study is to discuss the significance of the newly commissioned and staged Buddhist Kunqu Opera Innate Resentment. Mainly about the life of Ajase in Buddhist scriptures, the text of this play is compiled and edited by Hong Kong Chi Lin Nunnery. Subsequently, the Zhejiang Kunqu Opera Troupe adapted it into a Kunqu script. The production premiered at Hong Kong Chi Lin Nunnery in 2012. This play is based on three Buddhist sutras: Ajatasatru sutra 未生怨經, Mahayana Mahaparinirvana sutra 大般涅槃經, and Amitayurdhyana sutra 觀無量壽佛經. It tells about the story of Ajase, who held enmity with his father in previous incarnation, killed his father, and imprisoned his mother in this life. But he finally repented and became one of Buddha disciples. The theme and content is closely related with the practice and notion of salvation of the Pure Land Buddhist belief. In this study, I will explore the religious and theatrical connotation of Innate Resentment in the context of its theme and actual stage performance.
