William Walker Atkinson's excellent explanations of karma and reincarnation in ancient religions, Hinduism and Buddhism introduce both beliefs comprehensively. Atkinson authored this guide with the aim of introducing Western audiences to two of the key tenets of ancient and Eastern faiths. He explains the origins of both karma and reincarnation as beliefs, and how the religious sentiment behind both were refined and evolved by generations of adherents over centuries and millennia. After the historical aspects of the two beliefs are covered, the author embarks on a variety of philosophical discussions concerning the application of karma and reincarnation. Notions such the afterlife, and how the concept of justice exists and is applied to individuals, are examined in depth. As an introductory guide, Reincarnation and the Law of Karma excels at teaching the reader about the various qualities by which karma and reincarnation are defined.
