This article examines the artistic and philosophical essence of the concept of “bilig” (knowledge) in Yusuf Khass Hajibʼs “Qutadgʻu Bilig” and Ahmad Yugnakiyʼs “Hibat al-Haqoyiq”, which are important sources of classical Turkic literature. The study interprets the concept of “bilig” not as a simple collection of knowledge or information, but as a spiritual value that leads a person towards perfection, enlightenment, and the understanding of the Creator. Through contextual, comparative-typological, hermeneutic, and conceptual analysis methods, the article reveals the aspects of “bilig” (knowledge) related to enlightenment, wisdom, morality, and human spiritual development. It is demonstrated that in “Qutadgʻu Bilig” this concept rises to the level of an integral educational-philosophical system, while in “Hibat al-Haqoyiq” it is expressed mainly through moral teachings and ethical principles. The article also substantiates that both works are based on common ideas of self-knowledge, acquiring knowledge, and achieving spiritual elevation.
