What does it mean?

Astral projection is the act of living your body either on your will or not..(of course, it is an astral body that appears as substitute) everybody does it but few people can do it by will..and when you do it by will you can learn many stuff.. ^_^ know places and even learn new languages.. but you are not the state yet.. O_O
You can find many books about this topic, or even google it.. YAY I say google hahahaha.. When doing this trips you are sort of like a dream state, or trance in which you can move freely to where ever you desire to go. You can go to different planes, meaning the lower planes is where we all live.. *_* but there is a problem, since this all a mental trip.. and if you have fears they can manifest as evil creatures, and of course if you feel too much fear you will inmediately come back to your body.. ^_^ but well, I mean this is a long long long long topic, and it is the basics of instincts and wisdom in my opinion and where you can find more about yourself.. but get better information about it just go to websites that are more into this topic or books.. O_O though.. if you have more direct questions you can ask by all means..
