This book considers the connection between the world of mental health in the twenty-first century and the traditional concept of desire in Christianity and the Arts. It draws parallels between the desire for rest from anxiety among mental health sufferers with the longing for peace and happiness in Religion and the Arts. The author presents Biblical, philosophical and theological insights alongside artistic ones, arguing that desire for rest remains at the heart of spiritual living as well as mental health recovery. The chapters draw from historical and contemporary voices, including Plato, Augustine of Hippo, Julian of Norwich, Gerard Manley Hopkins, Simone Weil, Samuel Beckett, Tennessee Williams, Jean-Louis Chrétien, Eric Varden and others. The study demonstrates why longing continues to fascinate and grip individuals, creative endeavour and society at large, not least in the development of the understanding of mental health. It is valuable for scholars and advanced students of Christian theology and those interested in spirituality and the arts in particular.
