In the Mediaeval Ages, the presentation of the twelve Divinities and twelve votive prayers in the Medicine Buddha worship were made through classic scriptures. After the Northern Song Dynasty, Chinese monks wrote Foshuo xiaozai yanshou Yaoshiguanding zhangju yi《佛说消灾延寿药师灌顶章句仪》 (Ritual Spoken by the Medicine Buddha on Removal of Evil and the Attainment of Long life). Ritual regulations therein were practiced by Azhali (Acarya) Monks, an Esoteric sect in Yunnan, since the Ming Dynasty. The corresponding content of the ritual had changed compared with the Scripture itself, for example, the twelve Divine Kings correspond to the twelve Votive Prayers and twelve Bodhisattvas; the twelve Divine Kings were in charge of six kinds of crimes respectively, including Six Sensory Crimes; Killing Animals; Being Greedy for Love; Ten Evil Deeds and Five Heinous Crimes; Throwing away Food; Being Unfilial, Ungrateful, and Immoral. Ritual regulations, the contents of which were distinctly localized, could be practiced directly in the ceremonies.
