Religious books are among the most important foundations of sustainability which has always invited the man to good ethics in order to achieve salvation. Based on this, Avesta is the Bible of Zoroastrians and the ancient heritage of Iran which has always invited humans into three principles of thought, speech and good deeds. The purpose of this study is to examine the sustainability effects of the Avesta and then introduce it as one of the foundations of sustainability. This research is preceded by a descriptive/analytical cross-sectional study. After helping with various sources of sustainability, it can be concluded that there are lasting effects on the Avesta: Fighting demon and evil forces, Praise of martyrs and good forces, Praise of the homeland, defend the truth and invite to it. Despite the persistence of the Avesta, and because of the wide reflection of such themes in the poems of the Iranian poets, it can be considered as one of the foundations of Iran's land perseverance.
