Could someone tell me somemore about astral projection and all that stuff?
Could you give me a link and tell me what religion(s) it's in? Is it in christianity? Just some general info about it would be nice.
In occult traditions, practices range from inducing trance states to the mental construction of a second body, called the Body of Light in Aleister Crowley's writings, through visualization and controlled breathing, followed by the transfer of consciousness to the secondary body by a mental act of will
You might be more familiar with it being called "out of body experiences". It is when you're spiritual or astral body leaves the physical body. It also doesn't have to mean that you die.
I found this by searching for "astral projection" "string theory"
