The devon muktarealize is this one unlimited awareness is all that exists. In that the world, body and the first person i experience in this body, mind are continuing. They're appearing, disappearing, rising and falling. Enjoyer means the witness of all of that. I give it its existence, whatever existence it has. It's a pretty vivid experience. Consciousness only is not detached. The entire universe is nothing apart from you. Everything is yours. So why would you be afraid of anything? Nothing can kill you or damage you even what would you be fears of? What threat? What fear? What anxiety? What disease can affect you?
