Strangers in Paradox

We humans are not strangers to paradise. Only in its apparent reflection do we feel strange. A paradox is false because it goes against itself in fact. How is this different from saying that we are spiritual beings having a human experience when we can't know anything except our current (human) experience? We think it is real. Is it? If not, then it is a paradox; it is false because it goes against itself in fact. These offerings, gathered from A Course in Miracles and teachers like Eckhart Toll
