The Essence of Reality was written over the course of just three days in 514/1120, by a scholar who was just twenty-four. The text, like its author ʿAyn al-Quḍāt, is remarkable for many reasons, not least of which that it is in all likelihood the earliest philosophical exposition of mysticism in the Islamic intellectual tradition. This important work would go on to exert significant influence on both classical Islamic philosophy and philosophical mysticism.
Written in a terse yet beautiful style, The Essence of Reality consists of one hundred brief chapters interspersed with Qurʾanic verses, prophetic sayings, Sufi maxims, and poetry. In conversation with the work of the philosophers Avicenna and al-Ghazālī, the book takes readers on a philosophical journey, with lucid expositions of questions including the problem of the eternity of the world; the nature of God’s essence and attributes; the concepts of “before” and “after”; and the soul’s relationship to the body. All these discussions are seamlessly tied into ʿAyn al-Quḍāt’s foundational argument―that mystical knowledge lies beyond the realm of the intellect.
I read this book as a resource, as it gives access to the spoken word of a scholar in the year 1120. The translation is produced by a highly credible modern scholar after years of specialist research and study (unlike some of the better known and widely available publications on Sufism which have wandered far from the ´Essence´). The book has a brevity that arises from it documenting a dictation, but this does not detract from the book´s seriousness, weight and thought-provocation. I found it a fascinating and enriching read. Recommended.
