You can't get kicked out of your body. Your soul is attached to your body, possession IS a possibility in very rare cases but nothing to worry about if you protect yourself.... and even with possession you don't get kicked out of your body. Also the possessing spirit needs to use a LOT of energy to maintain control. It isn't like in the movies where once they are in they are all set and you need a priest to get rid of them! I know this from experience, a spirit didn't want to stop talking and I didn't protect myself properly. It took about 10 minutes to push the spirit out and that was before I had any real working knowledge of the spiritual realm (i learned to channel before i learned to shield... not the best order to go in) Something like that is very rare though, you should NOT be afraid to channel an entity if you prepare yourself. You WON'T end up in a mental hospital talking about god knows what. Many people go astral at night while they sleep. Very few people put up protections every night before they go to bed and they are not taken over in the middle of the night while not in their body. Prayer is also another way to protect yourself when getting ready to channel I agree with that. Jesus Christ has a wonderful energy and can also be very protective if you ask him. In order to let yourself go you would need to break the connection you have with your body (some of you know this as the silver cord when you go astral) and when that breaks you die. If you die while astral you do wander until you accept what happened and move on, but when channeling you don't leave your body. Also, other spirits do not have that "silver cord" connecting them to your body so they can't take it over and kick you out. Another spirit can't "cut the cord" on you there is no need to worry about that.
FallFromAStar I understand what your saying but I don't believe that can happen. You DO need to be careful when channeling an entity, but you can't loose your body and end up in a mental hospital for the rest of your life.
