The purpose of this study is trying to explore the Tzu Chi sign language drama and its implications of the aesthetic practice in the context of humanity education. We focus on the study of Sutra Adaptation of the Water Repentance, held during 2011 and 2012 in Taiwan's communities by Tzu Chi Foundation. The methodology used in this study is qualitative method, including content analysis according to the narrative texts, participant observation, and interviews. We found that different from the general traditional religious festivals or rituals, Tzu Chi Foundation adopted the concept of ＂big art＂, including music, literatures, linguistics, theater, video, and visual arts. The series of performing process of the activities included the steps of the preparation, the performance and the response of participants. The qualitative information also shows that the content of ＂Water Repentance＂ could stimulate the self-awareness and critical reflection of some participants, who were the community members across the barriers of themselves and interacted with each other through the effects of multi- perceptions, imaginations, and associations. Through the integration of the power from body, language and social action, the ritual inspired purification of mind in the context of moral theme. Those performances embodied the participants' aesthetic experience, and collectively created the cross-border work with the unique style of Tzu Chi humanity education.
