What does it mean for nature to be sacred? Is anything supernatural or even unnatural? Nature's Transcendence and Immanence: A Comparative Interdisciplinary Ecstatic Naturalism discusses nature's divinizing process of unfolding and folding through East-West dialogues and interdisciplinary methodologies. Nature's selving/god-ing processes are the sacred that is revealed as nature's transcendent and immanent dimensions. Each chapter of Nature's Transcendence and Immanence: A Comparative Interdisciplinary Ecstatic Naturalism shares a part of nature's sacred folds that are complexes within nature that have unusual semiotic density. These discussions serve to help restore a better relationship to nature as a whole through an innovative combination of research and ideas from a variety of traditions and disciplines. This collection not only introduces ecstatic naturalism and deep pantheism as sacred practices of philosophy and theology, but also invites a broader audience from a wide range of academic disciplines such as neuro-psychoanalysis, aesthetics, mythology, neuroscience, and artificial intelligence (AI).
