There are so many technical feats possible while out of the body but most are barely understood by the public at large. Including the interaction between our existance as radiation and the biology of our bodies and others. Most of these involve sonic and light radiation in frequencies that really do exist. Will infused by conscious thought. These things were well understood and perfected in ancient times
Eternal entrapment is possible but unlikely if our eternal self has sol as a guidepost. But hundreds of thousands of years and more of entrapment would have already occurred as part of manys pathway. The unfortunate reality is that entrapment has existed for many because of the nature of some once celestial entities. Who were more empowered than many others.
Evil entities human or other have an eternal existance as we do, for many of these this Is their eternal nature and they will never change, nor would they ever seek to. Many life forms that are a product of these entities may always have them as part of their eternal nature. They may always be here on this planet. The duality that they bring to our lives may not be neccessary at all for many of us. Eden once did exist here on this planet beyond duality as we know it, but their presence when here changed this balance.
Egypt saw the destruction of most of these entities on a celestial level in its time through Amilius who was an Egyptian king at that time. We know him through another name but he resided over planetary rulership at that time.
Life is entity based, in any species. We have an eternal self but sol is something that we may choose to become. This is a reality of our pathway that can be attractive to deny.
