While a spirit belongs to an evolutionary line
different from that of Man (that is, a spirit will never possess his/her
own body), a soul is the only rightful dweller and owner of a human
body.
Due to the low level of spirituality existing
at present in the world, the souls of most individuals encounter
some difficulties at the moment of the body’s death. Indeed, at time
of separation from its own shell, the soul is often unable to ascend
on its own to the higher vibrations needed to carry on with its
evolution. In fact most souls, not having received any preparation
on "how-to" while inhabiting the body, at time of departure remain
trapped in the familiar, physical surroundings in which the body
lived.
Luckily for the living, the greatest majority
of souls who wander on Earth are harmless, keeping themselves busy
with the aimless mimicking of the routine actions done in their past
lives. But, at times, their activity is such that it is noted by the
living among which they mingle, to the point of becoming a nuisance
to them.
Moreover, the strongest "anchoring" of the
soul with the physical world takes place when its departure has
happened in an unexpected or traumatic way. That is, when the death
of the body occurred in a violent manner, such as in a battle or in
a vehicle accident. Because of the shock of departure, the
non-spiritual soul could remain trapped, even for long periods of
time, in the location where the event took place. All the "ghost"
reports have to do with this mechanism. In fact, ghosts are always
the remnants of soul shells trapped in our physical world. They can
also be removed by the method described here.
