This book studies the phenomenological ontology of breathing. It investigates breathing and air as a question of phenomenological philosophy and looks at phenomenological questions concerning respiratory methodology, ontological experience of respiration, respiratory spirituality and respiratory embodiment. Drawing on the ideas of Maurice Merleau-Ponty, Gaston Bachelard, Martin Heidegger, Edmund Husserl, Luce Irigaray and David Kleinberg-Levin, the book argues for the ontological primacy of breathing and develops a new principle of philosophy that the author calls ?Silence of Breath, Abyss/Yawn of Air?. It asserts that breathing is not a thing- or person-oriented relation but perpetual communication with the immense elemental atmosphere of open and free air. This new phenomenological method of breathing offers readers a chance to begin to wonder, rethink, re-experience and reimagine all questions of life in an innovative and creative way as aerial and respiratory questions of life. \n
