All human incarnations or births have naturally a psychic being. It is only other types like the vital beings that have not, and that is precisely the reason why they want to possess men and enjoy physical life without being themselves born here, for so they escape the psychic law of evolution and spiritual progress and change. But these formations [the vital fragments of a dead person] are different, they are things that do not leave the earth and do not possess but simply attach themselves to some human rebirth (of course with a psychic in it) which has some affinity and therefore does not object to or resist their inclusion.
