It is well known that a human being consists not only of their physical body but also possesses higher aspects or components of their being. Esoteric literature refers to the physical body along with the etheric body, the astral body, the mental body, and the causal body, which together with the actual soul and spirit complete the sevenfold nature of a person. Various esoteric fields have produced a considerable amount of literature in recent decades that discusses the functions of these individual components. For example, it addresses the significance of the etheric body for health, the projection of the astral body during so-called astral travel or near-death experiences, and the impact of positive thinking on the mental body.
