This book lists, from the internet, all the known religions or non-religions of the world. Sects or denominations which exert great influence on the developing world or which challenge, encourage, or is the reason for, the anti-religion mentality of the developed countries are described in detail. The book addresses all peoples, and is in two volumes. Volume One deals with the Abrahamic and Dharmic religions. Volume Two deals with indigenous religions, left-hand path religions, the New Religious Movements (NRMs), alien based religions, non-sectarian and trans-sectarian religions, spiritual movements and practices, systems claiming not to be religious but which have the characteristics of religion and non-belief systems. It is hoped that those, who read these Volumes, will be able to see their religion or non-religion and those of others, more objectively, and, thus be able to manage the complexity of their interaction with the world views of people and cultures they encounter.
