In the book, Avini's Heavenly Treasure, the mystical discourse of classical literature and stability can be seen. Therefore, in order to better understand the work, which is a prominent example of contemporary sustainability literature, the intertextual relationship between mysticism and classical literature must be considered. This article uses a descriptive-analytical method with a comparative approach to examine the influence of Avini's texts on ancient texts of Persian literature, especially mysticism. For this purpose, mystical themes such as love, guardianship, secrecy, and satisfaction as the most important common mystical features of the discourses of Shahid Avini and mysticism are considered. The extent and manner of Avini's influence on these principles are examined in classical Persian mystical texts such as Masnavi, Koliat Shams and Divan Hafez, etc. The results of this research confirm that Avini, in order to describe his observations of war, has been influenced by classical mystical themes, especially Molana and Hafez, and has given these concepts dynamic and vivid aspects and has translated them in his work with contemporary and new formulations. In adapting the mystical themes of classical Persian language and literature, Avini goes so far as to show that the heavenly treasure book is based on the rich mystical literature of Islamic Iran in the contemporary world.
