People that have been gone long enough into the Light..
People that have been gone long enough into the Light nearly forget everything difficult about life, even if you are experiencing some tough things now. When you pass into the Light, this will be left behind because that’s not who you are.
Your Higher Self is what I would say immortal; your Higher Self continues its experiences and comes back into life again and again. This continues until we reach the point where we don’t have to come back anymore.
