RELIGIONS are thinking systems seeking to define and organise human relationships to god(s) and the universe. Since earliest times, humans have endeavoured to order their lives and the world into spiritual patterns. Religions outline ethical conduct and theorise about the nature of existence. They consider the possibility of an eternal soul and hypothesise on life after death. More than 95% of the global population subscribes to one of the ten major religions. Including folk believes and fringe sects, about 4000 different faith systems exist. Generally, individuals’ religious beliefs establish early in life, and most people do not easily change their religion or are interested in alternative views. Frequently members of one religion are indifferent or hostile to belief systems that appear incompatible with their own. Such attitudes have led to innumerable conflicts and bloody hostilities in history, some ongoing. A significant part of human thinking energy pivots on religious speculation. Yet clearly today, despite the great effort over such a long time, global peace and harmony are fleeting.
