Much of what Swedenborg describes regarding the nature of the afterlife syncs up nicely with Monroe's line of thought, although it is sometimes necessary to transfer Swedenborg's ideas into a more modern context, like that of Monroe and other modern explorers. 

I don't believe Swedenborg is describing hollow heavens.  Take a look at Doc's thread on Swedenborg's three stages of the afterlife.  Monroe's focus 27 fits into the second stage of Swedenborg's cosmology, and after this is where their material really differs.  In his third stage of the afterlife, Swedenborg describes an ascension into true heavens after focus 27, whereas Monroe doesn't really go into what happens, other than an integration with the Higher Self.  I'm really not sure what to make of it at this point, but I still have a lot of research and exploring to do.  However, it seems that maybe Swedenborg was on to something that perhaps Monroe wasn't open to experience.

It is understood that what Swedenborg discovered may not be 100% accurate due to his outdated belief system and limited capacity for understanding advanced concepts which we now take for granted.  However, it is quite easy to translate his findings into a more modern context, and it is plain to see that he knew what he was talking about.

Going by what I read thus far, Swedenborg would probably say that focus 27 corresponds to a level where spirits love each other, but they don't have a big interest in loving God.

Moving onto higher selves and the heaven Swedenborg  speaks of might have something in common. When you reconnect to your higher self you reconnect to God. You allow yourself to receive an inflow of God's spirit.

It is possible that Monroe and Moen didn't find out about Christ in the way Swedenborg did, because some people get turned off when you speak of Christ, and they wouldn't consider what Monroe and Moen have to say if they said a lot about Christ.

Some of these people got turned off about the Christ ideal because of how some fundamentalists have connected Christ to a fear-based and judgmental way of thinking that is inaccurate.
