I did not know that. I have personal certainty that eterioration can lead to body death. The body is programed to die if the spirit leaves. Most non Scientologists who exterorize do so when the physical body is asleep to avoid that stimulus/response mechanism and it is the only wat that they can create a separation from the body.
The spiritual Being becomes disoriented at body death because of past implants consisting of the electronic dissolution of memory and chaotic energies that overwhelm conscious awareness from between-life programed electronic personalities and destines that go into restimnulation. If these energies are not handled properly when exteriorized then true self is overwhelmed and disoriented by these unrecognizable unconscious energies they have sway over one's existence. Conscious awareness vibrates in unison with the physical body and non physical body and is the effect of both of nor operating at cause.
Scientology standard policy is to get mediacal treatment if one had a physical illness before they can have processing. People posting otherwise of healing with intention aloone are spreading disinformation. There is enough not to like about the Scientology organization without making things up.
