Experiencing this amount of love changes NDErs forever. Separation is merely an illusion of physical existence. Very much so. It would be very difficult to read all of the NDEs I have read and not come away with the idea that death itself is really an illusion. We are already in the afterlife right now.
Death is just a brief transition into another realm of existence.
In this respect, the NDE is very contagious. The profound, enormous love described and the utter lack of fear associated with the NDE are the important aspects that have changed me. Once a person understands death from reading about the NDE, there is nothing to fear except pain which is a normal and necessary instinct for survival. Before I read a single NDE, I was a fundamentalist Christian who was absolutely certain that upon death, I would be carried to the highest heaven to be forever before the very throne of God. I learned that one must become as Christ Himself practicing unconditional love for others to reach this level of bliss.
