The difference is when yo have somebody that is totally new to the world of astral projection. people do not need to have things added to their fears, which is the one thing they do not need, For example you have a 5 year child that is a natural at astral projection, As she as been doing since she was 2, and has never had any problems, as she does not know what fear is, Then someone comes along and tells her about all the scary crap on the astral planes, Just what do you think that is going to do to her, same exact thing with a adult just learning no difference...
