This study adopts an interdisciplinary approach combining mystical literature and architecture to examine the relationship between the concepts of the Seven Valleys of Spiritual Journey in the thought of Attar of Nishapur and the spatial organization of Iranian (Sufi lodges) during the Islamic period. Employing a descriptive–analytical method alongside interpretive (hermeneutic) analysis, the research investigates how the fundamental concepts of the Seven Valleys, Quest, Love, Knowledge, Detachment, Unity, Bewilderment, and Annihilation, are reflected in the spatial hierarchy and architectural components of the Khanqah, including the entrance forecourt, portal, platform (Suffah), cells, domed chamber, courtyard, and retreat space. It further explores how this correspondence contributes to a deeper understanding of Attar's conception of the mystical path. The findings indicate that the architectural elements extend beyond their functional purposes to embody symbolic and spiritual meanings. A meaningful correspondence can be identified between the sequence of architectural spaces and the successive stages of the mystical journey described in Attar's Seven Valleys. This relationship suggests that the was designed not only to accommodate religious and social practices but also to facilitate the experiential progression of spiritual development. The study concludes that a comparative reading of mystical literature and architectural space offers new insights into the semantic dimensions of Iranian s, interpreting them not merely as physical structures but as spatial manifestations of mystical concepts and the spiritual journey of the seeker.
