Spiritism : Of Latin spiritus spirit. Doctrines based on the survival of the spirit and the périsprit * after the death and which admits the possible communication with beyond, evoke deaths.  
Allan Kardec * exposes the spiritistic doctrines in its works. The hoomme consists of three principles: a body, a spirit and a périsprit (kind of body fluidic). At the time of the death, the spirit leaves the body accompanied by the perisprit. At a spiritistic meeting, the communication is established by the intermediary of the perisprits medium and spirit. The successive reincarnations constitute, with the eyes of spiritistic, the means of progressing.  
 
The périsprit : the astral or fluidic body is indicated by the spiritistic ones under the term périsprit which is also written perish-spirit. One can conceive it like a bond between the body and the spirit. At the time of the death, the périsprit and the spirit leave the body. It is by the intermediary of the périsprit that the communications with the beyond can be established.
