Background: Persian literature has always been a platform for proposing moral and educational concepts, and the great poets of this field have explained moral virtues by utilizing religious, rational, and mystical teachings. Sanai Ghaznavi is one of the first poets who moved Persian poetry from courtly praise and descriptions to educational and mystical themes, and presented a coherent system of moral thoughts in his works. This research, using a descriptive-analytical method and based on library study, has examined the manifestations of moral virtues in Sanai's poems and explained its impact on the formation and development of Persian mystical and educational literature.
Conclusion: The results of the research show that Sanai, relying on principles such as religion, the Quran and reason, established a moral system in Persian poetry, the axis of which is the purification of the soul, the search for truth and liberation from worldly attachments. Moral virtues such as pure intention, contentment, gratitude, inner purity and the connection of knowledge and action have a fundamental place in his works. These teachings laid the groundwork for the formation of the mystical morality movement in Persian poetry and were continued in various ways in the works of poets such as Rumi, Nizami, Saadi and Hafez
