Neville’s boldest claim is metaphysical: your own consciousness is the one reality, and the outer world is its faithful projection. Nothing “out there” is a cause; it is an effect of the state you occupy within.

Trace one outer frustration back to the inner assumption feeding it.
If your world reflects your state, what is it showing you today?
