Astral projection is when the soul leaves the physical body and travels to the astral plane (an intermediate world between heaven and earth).
Get rid of any fears you have:
Are you scared of encountering a demon ? Scared of irrational things such as what if you can't get back in your body ? Get rid of them. Learn to over-come them. Demons aren't as scary if you don't let them be and the silver cord between you and your body can't be broken.
Do it after you wake up in the morning:
Set your alarm clock an hour early so you feel a bit drowsy
Relax your body:
Let the tension out, get rid of any random thoughts. Relax.
Focus on a specific part of your body (your toes) and imagine that it's moving (curling your toes) but don't physically do it. Spread out slowly to the rest of your body.
Imagine yourself getting up and moving around your room while your still lying down.
You should feel vibrations. It's trying to channel you into the astral plane.
The above steps take a lot of practice and patience. Once you've managed to do it. Have fun and be safe. Explore the world and even outer space.
Getting back into your body:
The silver cord will always guide you back.
There are dangers associated with astral projection. Check back on my blog (sixpenceee.tumblr.com) I will create an entirely different post about that.
