The Dong Yuan Shen Zhou Zhi Bing Kou Zhang 太上洞神洞渊神咒治病口章

The author is unknown, but it was presumably composed by Taoist priests of the Dongyuan School in the Tang Dynasty.

It is a one-volume text included in the Zhengyi Section of the Daozang (Taoist Canon).

The scripture expounds the rituals and methods for Taoist priests to recite oral manifestos to summon gods, command ghosts, and cure diseases for people. It states that all illnesses and disasters befalling humans are caused by the harassment of evil gods, malicious ghosts, and calamitous stars, and thus one should summon divine generals, official soldiers, and star deities to subdue them.

The methods of summoning gods include rituals such as igniting the altar furnace, dispatching official soldiers, receiving divine officials, and closing the altar furnace. Among them, the section of "dispatching official soldiers" details the ritual of submitting oral manifestos (without written memorials) to invoke divine generals, official soldiers, and celestial stars. The practice of reciting oral manifestos already existed in the Eastern Jin and Southern Dynasties. Volume 10 of The Taishang Dongyuan Divine Incantation Scripture states: "When a grand master treats diseases, they only need to recite oral manifestos, not written documents, and heal silently. Additionally, reciting scriptures and performing Taoist rituals will surely cure all illnesses. If the patient’s condition is critical, one can also recite oral manifestos to repent for past sins, unravel karmic entanglements, and redeem transgressions on their behalf."
