SPIRITS
The problem with our current belief system is that the term 'spirit' has been bandied about without any proper knowledge of the subject. It is a general misnomer that all spirits are the energies of people who once lived here on Earth, but that is not true. A spirit is a being of light, energy or mass from which a physical form evolves. What this means is that spirits all have a physical form at one time or another be it here or elsewhere in the Universe.
The following is a brief description of the different types of spirit groups:
VISITING SPIRITS
Spirits are allowed to 'visit' their loved ones when permission has been granted by their angels. Permission can be granted for random or regular visits.
EARTHBOUND SPIRITS
There are three main kinds of earthbound spirits. The first kind are spirits who do not realize they are 'dead' or who refuse to acknowledge they have 'died'.
The second kind are spirits who request permission to 'return' shortly after 'death'. This is usually because a loved one's grief is so overwhelming it holds them here for an undetermined period of time. This is very common when children die before their parents for instance.
The third kind are spirits who are sent here on assignment by their angels to be with their loved ones during periods of crisis.
EXTRA-TERRESTRIAN SPIRITS
Extra-terrestrian spirits are not from this planet and are a very different kind of spirit indeed! Some of this diverse group is covered on this website (see Azureans, Zòltárz, Druáns, Ruáns, Zudéans and Sòltans).
WAYWARD SPIRITS
Wayward spirits are entities who travel between dimensions unauthorized. Poltergeists fall under this category.
