This book describes the concept of Karma in its historical development. The concept of Karma was already present in early Indian religious texts. But from the beginning it embraced broader sphere than terms between humans and gods. Therefore, later it answered for polytheism preservation, development of spiritual tolerance, and uprising of many sects in Hinduism framework. The concept of Karma remained rigidly irrelevant to any concrete religious world outlook. It was easily accepted by other spiritual movements being included into very different systems explaining arrangement of creation in whole. Karma concedes plenty of both gods and religions.
