One more thing that I meant to write in my last post, but forgot.
I took a "History of Religion" class in college, and I remember reading about a documented factual account of an ancient Chinese sailor who would go out of body in order to navigate the open seas. Apparently he would go into his meditative trance, leave his body, and soar over the open ocean searching for the route to the location that he would be traveling to the next day. Then, when he returned to his body, he would follow the same path that he had taken in spirit and find his way there every time!
I found that pretty interesting,
