Man, who is a social being, takes the shape of the society he was born into. At the same time, man shapes this container with his “language” and transfers it to future generations. Culture, which is a concept that has been transferred from generation to generation, is a whole that has emerged in line with the values of the individuals that make up the nation and the value judgments of other languages and religions with which they interact. The Turks, who preserved and glorified their own culture throughout history, converted to the Mani religion by Bögü Kağan in 762 and blended the values of this religion with their own culture. Huastuanift, which is a prayer of repentance belonging to the Manichaean religion, is one of the rare texts that have survived from that period to the present, expressing the teachings and social values of this religion. In this study, it is aimed to evaluate this text, which was written from a Manichaean point of view, in terms of the concept of “value”. For this purpose, the expressions in the text were handled with their contexts and analyzed qualitatively through the Maxqda Data Analysis Program according to the ten basic values and fifty-three sub-values within the scope of the Schwartz Value Scale. Thus, based on the text, it is aimed to reveal with which “social values” both Bögü Kagan, who preferred this religion, and the Mani religion tried to shape the Uyghur society, and which values the society/religion gave or did not give more importance to. Thus, the social values of the Uighurs, who belong to the Mani religion, were determined and a new perspective was tried to be gained about the old Turkish culture.
