In medieval Daoism, celestial writings are conceived as originally celestial signs and texts that have descended to earth, either by direct transmission of their form or by translation into worldly language. They are heavenly blueprints, of which only a few earthly beings are granted sight. The recipient is usually a person of great virtue who is able to decipher and deploy the revelations for the benefit of all. In this paper I examine a fifth century Daoist ritual, based on the scripture of the Taishang dongxuan Lingbao shouduyi 太上洞玄靈寶授度儀 edited by Lu Xiujing 陸修靜, intending to clarify the processes by which Daoists of the Six Dynasties constructed their rituals by means of the concept of celestial writing as well as certain sacred objects. I will focus on two episodes of the ritual, namely "Bestowing the Scribe of Eight March" and "Sealing the Scepter," which are related to two particular magical objects. The first goal of this paper will be to investigate Daoist ritual from the perspective of material culture. The second major goal will be to trace the development and transformation of the concept of celestial writing and to determine its relationship with sacred objects in Daoist bestowing rituals. I will also suggest that the symbolism and objectification of celestial writing in Daoism might fulfill the purpose of a certain group of Daoists who were trying to legitimize their religious authority through ritual. Through an analysis of the objectification of celestial writing, which played a crucial role in fourth- and fifth-century Daoist ritual, I hope to clarify not only the historical processes by which Daoists constructed their dispensations out of older traditions, but also provide a clear picture of the dynamic interactions between different traditions in medieval China.
