Not philosophically. Experientially. Right now, how do you know?
David Bohm thought the universe was holographic. Karl Pribram found the same structure in the brain. The Nag Hammadi texts said the world you see is a projection from a deeper truth.
The same idea. Three thousand years. Different doors. Nobody is connecting them in public. Nobody is giving people the direct experience to feel it rather than just think about it.
That's the gap. That's the campaign.
