Objective and illuminating, this treatise, written by Sufi leader Muhyiddin Ibn 'Arabi, presents a fundamental analysis of spiritual practice. Underscoring the importance of silence, seclusion, hunger, and vigilance, this guide demonstrates that these activities are both physical and spiritual. Providing the necessary tools for an enlightened life, this dual-language edition incorporates the first critical edition of the Arabic text, gathered from the best-surviving manuscripts. An introduction, and translation of chapter 53 of the renowned Futuhat al-Makkiyya, are also included.
