Ghosts are an interesting subject, and one that nobody is neutral about.  What is especially funny is when a non-believer struggles to justify their non-belief when an encounter with a ghost is their first personal encounter with the spiritual!Defining what a ghost is not only clarifies what we are talking about; it also shows the pure logic in the fact of their existence.  Learning how to deal with them is an essential part of spiritual growth.This is a subject in which many people have devoted years of research, experience and debate.  And we'll dust off some of the surface here. Blessed Be!
