Özet:

and II. The Uighurs, who are the political and cultural followers of Köktürk Kağanlığı, have had important positions in the geography in which they live, with activities such as agriculture and trade, contacting and developing different cultures.  The Uighurs, who have left profound influence on the peoples they have contacted, have added wealth to the Turkish language with literary products they have developed especially on the basis of religion. The Uighur who adopted religions and doctrines such as Buddhism, Manichism, Christianity and Islamism, according to these religions and doctrines, thanks to the Uighur priests who entered the search for the Turkishalization of the concepts that describe the philosophy of Buddhism and Manichism, the foreign religious terms of these doctrines have Turkishalized using various methods. Among these methods, the relevant religious terms are transmitted using the concepts belonging to Ancient Turkish faith, producing Turkish correspondence and using the equivalent Turkish word and the foreign religious term together. In the Orhon Turkish period in which the Turkish language is written, the "state" and "people" are in the center of the word-qualitative existence, while in the Old Uyghur Turkish period there is a word-qualitative existence that reflects the philosophical dimension of thought.  The fact that the Turkish language has the power to speak the philosophical teachings such as Buddhism and Manichism is worth considering in terms of indicating the processing of this language. In this direction, for the first time in the ancient Uyghur Turkish period, Altun Yaruk etc. described the basic philosophy of Buddhism. The erdöktäg expression we present through texts is one of the terms in the religious terminology of the Turkish language.  In Buddhism, this term, which means “the main aspect, the essence of existence”, only indicates the awakening of the perception that will be achieved by Buddha. This study will try to reflect the importance of the term in the Buddhism according to the texts the conceptual and linguistic value of the erdöktäg expression which is testified in the ancient Uyghur Turkish texts.
