The San Mei Shen Zhou Zhai Qing Dan Xing Dao Yi 太上洞渊三昧神咒斋清旦行道仪

With an original note stating "lacking the rituals for noon and evening", this text was revised and finalized by the late Tang Taoist priest Du Guangting.

It is a one-volume work included in the Rituals and Ceremonies Section of the Cave Mysterious Division of the Daozang (Taoist Canon).

The text records the Taoist ritual procedures for priests to perform the Dongyuan Samadhi Divine Incantation Fast in the early morning and recite The Taishang Dongyuan Samadhi Divine Incantation Scripture. It claims that performing this fasting ritual can pray for world peace and the salvation of the souls of the deceased. The ritual sequence includes chanting praises, reciting incantations, offering incense, paying homage and repenting, performing the "Void-Stepping" circumambulation, delivering prayers and making vows, and so on.
