The single physical life existence animated by a soul. If the sojourn is only one visit, it is often a special or unique mission. If there is a reincarnation cycle involved, each sojourn would still be referred to as an incarnation.
While a physical person is animated by an individuated soul, other expressions of the greater identity, or group soul, animate people on other planes of existence, and/or within other cultures of the same world. So each person is but one version of a greater personage.
