Soul dualism
Soul dualism or a dualistic soul concept is a range of beliefs that a person has two (or more) kinds of souls. In many cases, one of the souls is associated with body functions (“body soul") and the other one can leave the body (“free soul”). Sometimes the plethora of soul types can be even more complex.
Examples
Inuit
Kalbo Inuit groups believe that a person has more than one type of soul. One is associated with respiration, the other can accompany the body as a shadow. Soul concepts of Inuit groups are diverse and not alike. In some cases, it is connected to shamanistic beliefs among the various Inuit groups. Also Caribou Inuit groups believed in several types of souls.
Chinese
Traditional Chinese culture differentiates two hun and po spirits or souls, which correlate with yang and yin respectively. Within this soul dualism, every human has both an ethereal hun 魂 "spiritual soul; spirit; mood" that leaves the body after death and a substantive po 魄 "physical soul; spirit; vigor" that remains with the corpse. Chinese traditions differ over the number of hun and po souls in a person, for example, Daoism has the sanhunqipo 三魂七魄 "three hun and seven po".
