I was researching this as well, but I figured out easier way of doing this.
Easiest way to achieve OBE is during relaxation deep or Sleep paralysis(thats the secret).
Some people can achieve this through smoking (u know what), I've noticed, when relaxed.
A relaxed body without SP also works, need experience in meditation, to reach
thoughtless state of mind, you are basically depriving yourself of your senses, and
the brain thinks it need to go to bed, and hence the ILLUSIONS.
Hate to say it, all it really is, is a another form of "dreaming" or lucid dreaming", just
another form of it.
But astral project/OBE IS NOT LUCID DREAMING. May look like it but its not.
Cause in lucid dreaming,(done lots of time) its your own personnel sandboxed
WORLD where you are god, you can do whatever the hell you want.
While OBE/Astral, there is limitation, in which you explore, different
layers of the world, in which lucid dreaming doesnt have. Has a different
feel to it, very realistic and vivid, very much like reality, while
people who are trying to be LUCID they have to use reality checks.
Obe/astral is about the same thing. All you need to do is pop out of your body
once you hit SLEEP para vibrations. Then you are free you explore your mind.
Google how to astral project / or how to OBE, its usually the first link.
Or here is simple basis of trick
1. sleep 4-5 hours, set alarm to wake you up.
2. wait about 1 hour before go back to bed. (read a book)while awake.
3. Back to bed, this when SP occurs, now practice exit technique,
easiest is to roll out of bed techi, since you know the sensations,
all thats needed now is to visualize it.
4. DONE>
Theres really nothing religious/spiritual about it, or its not evil
in anyway way, since its all occurring within your mind.
Its a dream.
Now if you schizophrenic problems, or mental problems, or "FEAR" inside your mind
, you might not like the experience, cause your mind brings forth the "FEAR" to
LIFE, and ITS VERY REAAL and the FEEL IS TOO, cant harm you anyway, cause its a dream.
I had a nice WEBSITE about astral/obe, that I backed up the
entire site in time, about astral, same as above, their
site dont exist anymore, guess they couldnt pay it anymore, good thing I backed it up in time.
When I have time, ill try to write up a guide with pics from their site.
