This study explores the metaphorical use of “pilgrimage,” or zīyārat, in Persian mystical poetry, particularly in the works of Ḥāfiẓ Shīrāzī, Maḥmūd Shabistarī, and Ṣāʾib Tabrīzī. The poets transcend the term’s traditional religious implications, imbuing it with a profound spiritual resonance. Ḥāfiẓ Shīrāzī employs the metaphor of pilgrimage in association with the “tavern” and “wine house,” using “wine” as a symbol of divine love and knowledge, thus revealing a spiritual journey surpassing literal religious adherence. The paper further delves into the usage of pilgrimage as a spiritual journey towards the divine shrine: the human “heart.” Shabistarī and Ṣāʾib Tabrīzī’s works conceptualize the heart as an object of pilgrimage, reflecting humans’ inherent sacredness and divinity. This interpretation expands the notion of pilgrimage beyond a physical journey to a metaphysical quest for self-understanding and compassion. Moreover, the research identifies metaphoric language’s dual role in Ḥāfiẓ Shīrāzī’s work: a protective strategy and a criticism of formalistic religious practice. The use of metaphor serves not as a rejection of religion but as a nuanced challenge to rigid religious interpretations. Remarkably, the metaphorical interpretation of pilgrimage extends beyond the confines of literature and has integrated into Iranian vernacular, adopting a new meaning to imply “visiting individuals.” The humans’ divine nature underpins this linguistic transformation; thus, visiting someone is interpreted as a spiritual journey to their heart. Nevertheless, potential criticisms arise from these interpretations. While poetically compelling, they may offer an overly romanticized view of the spiritual journey and may not resonate with all due to cultural, religious, or personal constraints. The paper provides insight into the transformative power of language in Persian mystical poetry, emphasizing the metaphorical use of pilgrimage despite potential limitations and criticisms. It demonstrates poetry’s ability to push boundaries, provoke thought, and invite deeper spiritual exploration.
