Re: no_thing
I do not think if I understand your question. By "being manifest and experiencing transient things" I mean the world we exit in ... the universe ... matter and energy. I think spirit manifests here experiencing itself. and souls combine with physical forms to experience "manifest and intransient things".
The world you describe sounds beautiful and it is my belief you cld experience, perhaps even create such a world for yourself -- perhaps even here :) but my feeling is that from even such a lovely world as that, eventually you wld want to move on.
What I was trying to say was that I do not wish to reach the time of no-thing and emerge on the other side unmanifest. I wish to walk into what I call, like many other people who may or may not mean the same thing, "new heaven, new earth" which may kinda be like what you described, tho maybe not summer all year long and I am not sure if people can run as fast as deers but if they well I wld imagine you could :
However, it probably will differ from the world you describe in one very major way. It cannot always be that way because everything changes.
