Spiritualties take a variety of different shapes. ‘Types and traditions’ shows a way of categorizing different forms of spirituality that can be applied across boundaries, and illustrates this with examples from Judaism, Christianity, Islam, Hinduism, and Buddhism. How and why does such a range of spiritual traditions appear within each religion? How do they develop? Why do some survive and others fall? The notion of a ‘secular saint’ has become more common recently. The term refers to someone who, irrespective of religion, is respected either for their selfless contribution or their inspiring life, e.g. Mohandas Gandhi, Cicely Saunders, Martin Luther King, Jr., and Dag Hammarsköld.
