why think that you leave your body? yes it feels that way, but why wouldn't all these astral/causal worlds be IN your body. the bible says; your body is the temple of god.

when you travel to other worlds, you actiually need a master to guide you. every far spiritually progressed man would say that. it is not the danger of not coming back. you are so attached to this world that you definately will come back. it is that these other worlds, have heavens and hells. the hells will look like heaven and the heavens will look like hell.

in those worlds you don't have the power to discriminate, for you are not familliar enough with it.

the fear not to come back is soo not realistic (when you see the bigger picture). it;s just ego. but it is very hard to lose that fear.
