Sri Aurobindo
Letters of Sri Aurobindo
Volume I - Part 5
Fragment ID: 10758
The fragments [of a dead person] are not of the inner being (who goes on his way to the psychic world) but of his vital sheath which falls away after death. These can join for birth the vital of some other Jiva who is being born or they can be used by a vital being to enter a body in process of birth and partly possess it for the satisfaction of its propensities. The junction can also take place after birth.
