…in general ths is a very authentic series but with a big mistake: When Jim Clancy dies after being shot he should have entered another body named Sam and lived some more episodes together with Melinda Gordon (Jennifer Love Hewitt). This is impossible after the spiritual laws and if performed on purpose smallens the positive things of the series.
This is explained in the Greber book on page 311:
In connection with ‘raising the dead’, I must tell you something that may surprise you. In all cases of so-called ‘raising the dead’, both those mentioned in the Old Testament and those performed by Christ, the spirits of those who were thus raised had not actually passed into the Beyond. No one who has actually died can again come to life; his spirit can never again take possession of the body from which it departed in mortal death. This is a Divine law that admits of no exceptions. As soon as a spirit crosses over into the Beyond, its race on earth is run. Its earthly destiny is irrevocably decided. Only by rebirth can this spirit ever again take on human form.
