This is the first book to examine the Subtle Body - a model of subjectivity found in esoteric, eastern and western religious and philosophical traditions - from a transdisciplinary and cross-cultural perspective. It considers this radical form of self (and the aesthetic and ethical relations that emerge from its proposition) as enabling an innovative reconsideration of the dualisms at the heart of western discourse: mind-body, divine-human, matter-spirit, reason-emotion, I-other. Emerging from this consideration is an interrelated aesthetic-ethic that promotes an understanding of embodiment that is not exclusively tied to materiality (corporeality). This perspective posits an individual as inherently intersubjective, creative and open. It presents subjectivity as relation: a dynamic relation that does not erase individuality while being inclusive of relations with radical alterity (including the divine). The text considers subtle bodies as found in various traditions including Yoga and Tantra traditions, The Theosophical Society, Renaissance Hermeticism, Sufism and even within the work of contemporary philosopher Luce Irigaray. Conceptual interrelations are traced across the disciplines of religion, philosophy and art history/theory, with a particular focus on its relevance to contemporary feminist religious studies/philosophy, mysticism and theories of desire.
