Question: What about guides, angels? Are they part of that vision that comes out of the brain-mind?
They are all part of the mind's imagination only. Because one thing is guaranteed: the mind, which has come out of the Divine due to imaginations, has also visualized how to go back. So it will definitely go back to the Divine. Everybody's mind will go back one day. The way it has visualized, it starts going like that. So if you use such thing just for concentration and do not bother what it is, then the mind recedes and goes back quickly. Otherwise, if you try to analyze, mind gets involved. It's a mind-boggling thing, never-ending process.
