This article is the result of many years of research by the author of the problem of the origin of Khoja Nasreddin, a popular character in the folklore of Central Asia and the Middle East. The results of the study revealed a whole layer of the semi-everyday Sufi tradition of teaching stories, spread among the closed Sufi brotherhood of Khojagan. The origin of this original tradition, as a method of spiritual development, goes back to the foundation of the Khojagan brotherhood in the 9th century, and it reaches its color by the end of the 14th century, becoming the property of the broad strata of society during this period due to the appearance of the Naqshbandiyya Sufi brotherhood in Bukhara. During the research, the author collected and analyzed more than one and a half thousand stories about Khoja Nasreddin, belonging to the modern folklore of the peoples of more than twenty countries of the world. Such a wide geography of the spread of stories about Khoja Nasreddin became possible largely thanks to the Great Silk Road. The variety of plots, their repetitions and various variations found in the folklore of different countries prompted the author to conclude that there must be original, that is, authentic versions of these stories. The search and identification of authentic stories about Khoja Nasreddin led the author to the discovery of a lost and long-forgotten Sufi method of comprehending the truth - the "Tariqat of Khoja Nasreddin".
