"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."
There are many things often quoted from the course, perhaps loosely from memory, something that stuck in your head when you read it. But which really is not well thought out or deeply considered. "Heaven is not a place" is one of those things, which has been widely misunderstood.
See, places, in general, are an aspect of spacetime. In space, there are many places. Over here, over there. My place, your place. Many places. There are places in spacetime because space separates everything out, based on the idea of separation and lack. But you have to remember, that spacetime itself is nothing but an illusory ego belief. Space time, does not exist.
Now, when Jesus says that Heaven is not a place, he is merely referring to the fact that SPACETIME does not exist in Heaven. There is no localization or confinement to one area, in heaven. There is no cut off piece of it that is kept apart from others and labelled as if it's not the rest. It's all joined. It's one. Heaven is one huge infinite unlimited PLACE, that has no separate places within it. Everything is everywhere.
It's perfectly legitimate to say it is not a place, while still not contradicting the fact that Heaven IS A SOMEWHERE, a locale, a home, somewhere that you can actually BE, live, dwell, and experience reality. It is actually a something, a somewhere. It's just that it is not limited. It is all things real and everywhere real.
But heaven is not an isolated place. It's not a United States. It's not a Russia. It's everywhere without limit. That's why it is "not a place". It's not a separated off thing with a label to distinguish it from the rest.
Especially if you consider the fact that space-time is a belief that is unreal and an illusion. There is no space or time. Both are made up. Which means ALL PLACES within space and time do not really exist. So every single PLACE that you ever thought of as being a place, is not REALLY a place. In fact, it is not a place at all. It's a nowhere. Spacetime is the idea of NOT EXISTING FULLY ANYWHERE, which is why every "place" within it is NOT THE WHOLE.
So when you throw out spacetime and shove it in the trashcan, what are you left with? You are not left with places. You are not left with isolated boxes and confined locations. You are only left with the only REAL SOMEWHERE, the only ACTUAL REALITY, the only REAL PLACE that you can be. And that is Heaven.
Absolutely. Heaven is the ONLY REALITY, the ONLY REAL PLACE you can truly exist. That's why "You are at home in God, dreaming of exile". You can't leave Home. You can't leave heaven. But you can DREAM of being OUTSIDE of it in another WORLD, full of places, where none of those places are really anywhere.
Where is Jesus? He is IN HEAVEN. There are so many references in the Course to being IN heaven, in stark contrast to being ON the earth. Jesus makes it clear that there are two WORLDS, they are two PLACES, they are OPPOSITES. "Heaven remains the one alternative to the strange world you made" for example. "Earth, Heaven's opposite in every way." "Heaven is all that remains."
When the world disappears, which it will, where will you be? When there is no world, where do you live? When space and time collapse into nothing, where are you then? When the world spins "into the nothingness from which it came", and "gone is place, as well as time", where will you be? How will you exist SOMEWHERE, in a real SOMEWHERE, without any PLACES to exist? You MUST have a home, a real somewhere that you can experience. Where is that? Where is Jesus, in his home, not of this world? He's is in Heaven.
Heaven absolutely 100% is a PLACE. You can GO THERE. You already are there but you don't realize it because you're sleeping and pretending not to be in Heaven. When the dream world stops existing, you will wake up IN HEAVEN. It's reality. It's a REAL PLACE. It's where God lives. It's not "merely" an "awareness of perfect oneness", as if to imply you will KEEP THE WORLD and have some kind of heavenly mindset at the same time. Newsflash... not possible. "You cannot remain in this world with this knowledge."
There is no world. Central lesson. The world is NOT A REAL PLACE. When there is no world, the ONLY PLACE LEFT, to live and experience and be real, is Heaven. Heaven is THE ONLY PLACE THAT EXISTS. There is no other place. All other places are illusions.
So absolutely, it is false to interpret Jesus as saying that Heaven is NOT A PLACE. That's not what He means. He means only that it is not SPATIAL. And in that He also acknowledges that ALL SPATIAL PLACES ARE ILLUSIONS, which is why Heaven is NOT AN ILLUSORY PLACE. It's real.
It's your home. And it's the ONLY place that you can ever really exist.
Notice the quote also ends "Nothing OUTSIDE this Oneness, and NOTHING ELSE within." Which means heaven as a place does not coexist with THE ILLUSORY WORLD. There is NO WORLD outside the oneness of heaven, the place of heaven. The world you THINK exists right now, is an illusion of being outside the Kingdom. It does not exist. It is not HERE NOW. You are not in a place NOW. You WILL be in a place when you wake up to reality.
