The aim of this book is to contribute to the elucidation of an important but much neglected theme in comparative religion and mysticism: that of transcendence. The book intends to shed light on the meaning of transcendence both in itself and as the summit of spiritual realization, taking as starting point what three of the world’s greatest mystics have said or written on this subject. Shankara, Ibn Arabi and Meister Eckhart, each of an immense importance within their respective traditions, have been chosen for this study in as much as both the conceptual and experiential aspects of transcendence figure prominently in their articulated writings and discourses; each one has, moreover, expressed himself in a manner that is at once authoritative – bearing witness to his personal realization – and detailed, thus allowing for extensive analytical treatment of these aspects of transcendence.
