This interdisciplinary book examines the nature of spirituality and the role it plays in the search for meaning. Spirituality is a loving tendency towards the sacred. In a secular environment, the sacred is taken to be a power greater than self. In a religious environment, the Sacred refers to God, or Higher Power. The book examines the developments of the s/Sacred in great works of art and literature, as well as in medicine, theology, psychology, philosophy, and religion. Spirituality also functions as an unloving tendency towards disunity, or a force for evil. The first part of the book examines the ways of the spiritual as a force for good and evil. We have just witnessed one of the bloodiest centuries in human history. The experience of two World Wars leaves a legacy of brokenness: “Where Nossack’s reminiscences bore poetic, compassionate, and personal witness to the disaster, Eliot’s poetry reads more like a sacred and religious poem taking contemporary Western European civilization to task—much like the biblical prophets of old—for its spiritual bankruptcy.” Albert Einstein, Edvard Munch’s Madonna, and Carl Jung’s ‘unconscious’ touch the curve of the Sacred in more promising places. The second part examines how the search for meaning works. The distinction between being human and being a person plays a central role in the life of the spiritual; “...the spiritual is manifest in the activities taking place in the central self. The central self is the locus of all thoughts, feelings, acts of reason and judgment, conscious and unconscious processes alike. The central self is the place where social relationships and environmental relationships are processed. The essential feature of the central self is that it does not exist outside these processes.” The same spiritual energies that light up great works of art also light up our destructive side, only the associations’ change.
