This study explores the distinguished Persian Sufi mystic Shaykh Maḥmūd Shabestarī’s Golshan-e Rāz, or The Rose Garden of Mystery. Adopting a hermeneutic approach, it scrutinizes the intricate spiritual journey towards DIVINE realization delineated in Shabestarī’s poetry, utilizing qualitative content analysis of original texts and interpretations by scholars such as Lāhījī and Ibn Turka Iṣfahānī. The main question the paper addresses is this: “How can the spiritual journeyer overcome obstacles—particularly ‘otherness’—and achieve UNITY with the DIVINE Essence within the framework of Islamic mysticism, as interpreted through Shabestarī’s teachings in Golshan-e Rāz?” To answer this inquiry, the paper addresses pivotal questions concerning Shabestarī’s depiction of the spiritual journeyer’s path, its stages and challenges, and the critical role of the human form in DIVINE manifestation. The study underscores the necessity of overcoming duality and distinction, alluding to the transformative nature of the journey that necessitates self-purification and the cessation of otherness. Findings from this study provide an enriched understanding of Shabestarī’s thought, contributing to the discourse on Islamic metaphysics. It presents valuable insights into the spiritual journeyer’s path, offering a comprehensive interpretation of the challenges, practices, and transformative experiences leading to DIVINE realization and UNITY.
