Reincarnation and the Law of Karma is a classic Hindu religion study by William Walker Atkinson. By "Reincarnation" we mean the repeated incarnation, or embodiment in flesh, of the soul or immaterial part of man's nature. The term "Metempsychosis" is frequently employed in the same sense, the definition of the latter term being: "The passage of the soul, as an immortal essence, at the death of the body, into another living body."
