It’s just that there is a lot more Time and Space in the temporal universe that makes it appear to also be separate which is what our physical senses tell us…and too little awareness of consciousness which could unify it all.
Both realities are real of course, but the deeper, wiser and actually more scientific viewpoint (the narrow religiously scientistic viewpoint is that only time and space are real) affirms the more primary, inclusive and graciously experiential oneness of the world.
Contemplate that and it will become the much more real reality it actually is.
