From what I've been able to determine, reincarnation is a false belief, a false religious belief. There is an afterlife for everyone and it has many planes and realms with schools and teachers that anyone of any level of development can go to and learn to advance onward and upward from there. The spiritualists of the mid-1800's to mid 1900's channeled many departed spirits and none spoke of reincarnation. Then somewhere in the 1930's and 1940's there began this talk of reincarnation.

"As it was in the olden time, so will it be ere another generation pass away. Drujas will teach that the spirits of the dead go into trees and flowers and inhabit them, and into swine and cattle and birds, and into woman, and are born over again in mortal form"....Oahspe 1882

Just say no to reincarnation, if you find yourself in the afterlife and someone is urging you to attach yourself to some body and take over their life, as depicted in Journey of Souls by Michael Newton, just say NO. They will tell you you need to do it, in order to advance faster, but while you are attached to the body, you are missing out on the learning you could be receiving in the higher planes from the advanced teachers there.

It has been said that we all have spirits of the departed attached to us. They like the feeling of being physical and are afraid to move on away from the low earth plane.

"As there are on earth paupers and vagrants and beggars and criminals who are druks, so are there in hada spirits that are a great trial to both mortals and angels. And they inhabit mortals and the houses that mortals dwell in. Some mortals have one or two of them, some a score, and some have hundreds of them. Some of them continue to inhabit mortal dwellings long after mortals have abandoned them, even till they fall in ruins. And whoso cometh into such house, the drujas come upon him to live on him and with him.

And if a mortal have greater wisdom and strength of soul than the drujas, he ruleth over them to a good purpose, reforming them and raising them up out of darkness and helplessness.
But if the drujas have greater power than the mortal, they they pull him down in darkness, making of him a man to lust after the affairs of the earth."
