The quick and simple answer is "within," but the Truth is that there is not a location for IT is unlimited Presence. It is only the clever trickery of the mind that offers this view of "elsewhere" and "otherness." We are IT.
IT is us. There is no separation. Only the conditioned layers we've constructed over millennia obscure the Reality of what we are, Spirit "Beings" engaged in the perfect outpouring of Source through us as us.
Your use of the word "relation" is precisely how the mind engages us in misdirection. This world of misperception is relational, broken into parts and pieces, judgments, labels, kinships, distinctions, longings, rejections, fear, and polarization (success/failure, win/lose, work/rest, give/take, love/hate, etc.). Here, we have forgotten our true and original nature as one in The One, eternal and limitless.
We deceive ourselves that we are autonomous, separate beings, even though we see ourselves as being trapped in an often painful and frightening world not of our making. We blame others for everything we don't like, yet take credit for all that pleases us. Yet it is all a mind game.
In fact, this world that we perceive with our senses IS of our own making. It is our own thought bomb with its disastrous fallout, changing constantly from this to that and that to this, an impermanent, limited thing. It contains all the false perceptions we've accumulated in our effort to make a place of comfort and safety.
But, of course, we've failed precisely because it is WE who made it, forgetting the inherent perfection of all that is as it is. We cannot improve upon perfection, and we forget that we are already perfect beings created in the image of God/Source/All That Is. We ARE the spiritual world.
We have only to remember our true nature. I am Sirius.
Imagine our universe is a computer program. On the computer there is another program called heaven. They can both use the same computer, while they act independently, do share certain information.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
