Abstract
The article analyzes the baksy (clergyman in Tengrism), considered representative of the Tengrism era, and the problem of its study in Kazakh science. The necessity and benefits of the baksy are examined, as well as the works of researchers who contributed to the definition of the professional personality of the baksy. It is known in science that traditions such as pre-Islamic theology, Mithraism, Zoroastrism, and shamanism are little studied and analyzed, and are of interest to society. Starting from the Turkic period, the assessments and conclusions given by famous scientists to this belief, which has its place in the formation of the Kazakh people as a nation, are differentiated, and the features of the baksy are critically analyzed. The authors used hermeneutic, descriptive, historical narrative, and historical-axiological methods when they considered it necessary to study in domestic science one of the pre-Islamic beliefs of the Kazakh steppe - baksy. As a result, it was assessed and weighed that the attitude towards the ancient art of baksy has changed today. In addition to knowledge of the history of the religious worldview, the integrity of the religious worldview is also important. At the same time, it has its significance in strengthening national identity.
