Just a thought...I keep learning of people experiencing episodes of intense light of a spiritual nature. Light episodes may be some form of spiritual communication or expression. Body sickness or medical problems, when looked at through the perspective of spiritual eternity is merely a manifestation of a spiritual sickness. This derives from the belief that the body is real and offers one salvation, which is subject to eventual disillusionment. Spiritual reality however is eternal. When we learn to only identify with our spiritual and eternal truth, it is impossible to feel pain. Pain is attachment to the body and our choosing to identify with the body and the insane world created by man's ego. The body is the ego's interpretation of salvation. That probably won't make any sense to you whatsoever and of course you should always go get checked out by a doctor. Peace, MH.
