Some people recall and quote that Heaven is supposedly not a place or a condition, but just an awareness of perfect oneness. Well, if you go read the full paragraph, it says otherwise:
"THE KINGDOM OF HEAVEN IS THE DWELLING PLACE OF THE SON OF GOD, who left not his Father, and dwells not apart from Him. Heaven is not a place nor a condition. It is merely an awareness of perfect Oneness, and the knowledge that there is nothing else. Nothing OUTSIDE this Oneness, and NOTHING ELSE within."
Now, when he says is it not a place, what he means it is does not involve SPACE OR TIME. Everything that you usually think of as a "place" is actually the idea of "something is over here, but not over there, because they are separate". So like the USA is a place, the Atlantic ocean is a place, the moon is a place. But in Heaven, there are no separations, and everything is everywhere. So you can't have a "local" location there, or some part which is separated off as a discrete "place" separate from the rest.
Instead, Heaven is actually a PLACE where you can live, exist, be, share, have, extend, and live forever. You can DWELL there. You can BE there. It is existence! It is where God is. His being is the location of your soul. But the difference is, it is not a place of SPACE or TIME, and there are no 3D forms or objects. It is pure being/mind/spirit that transcends spacetime.
If you then consider that anything outside of the Kingdom is an illusion, and the "world you made" is an illusion of being outside the Kingdom/God, and THIS WORLD EARTH is therefore an illusion, it is an ILLUSION OF PLACES, due to being based on spacetime, where everything is separated out. And therefore this world actually represents the idea that EVERYTHING IS NOWHERE, and nothing is everywhere (absence of God), and therefore this "place" that you like to think of as a place is actually NOT EXISTENCE, is NOWHERE, and DOES NOT EXIST.
So to think of Earth as "a place" is wrong. And to think of Heaven as NOT a place, is wrong. We have it all backwards. Heaven is THE ONLY PLACE YOU CAN BE AND LIVE. And Earth is not a place at all. It is oblivion.
We have to be careful about this because frequently I've heard people saying Heaven is only a state of awareness, not a place. That leads them to conclude you can't GO THERE, you can't be IN HEAVEN, and it's not somewhere OTHER than this world. That it's not even a world at all. "Beyond this world is a world I want" and "you cannot see two worlds" tells us IT IS a world. An existence.
So when we say Heaven is not a place we end up believing it's just a state of mind, and then you start to think ok, I can be IN HEAVEN while I am IN A BODY. And I can be totally awake inside a dream yet not having a dream. And its possible to have awareness of total oneness while IN a body. IT IS NOT POSSIBLE. No-one who accesses the knowledge of Heaven and overcomes perception and the "body is a dream" illusion, can possibly stay in a body and be IN Heaven. If you want to be IN heaven you have to actually "leave this world" and GO THERE. Or in other words, recognize THIS WORLD IS NOT A PLACE, and overlook it (forgiveness) and realize you are actually IN heaven.
"Heaven is here now". THIS WORLD IS NOT HERE NOW.
Heaven is the ONLY PLACE you can be. "There is no life outside of heaven."
Where is Jesus? Why isn't he in a body walking around THIS "place"? Because he's not here. He's in Heaven.
