The "Urim & Thummim" were perhaps Joseph's own eyes, which in a mystical state of consciousness could "see" the visionary "plates." He lost these "gifts" for a time.
If Joseph made the plates he had in his possession, then didn't he lie in saying otherwise? Maybe there is more to it, which ties into the mystical nature of his visions.
The hard problem of consciousness may lead us to an irreducible mysticism in the nature of the mind and body, namely that they are two sides of the very same one thing.
Nihilism is a philosophy that says that life is meaningless. It says there is no objective meaning, intrinsic value, or purpose in life. What does mysticism and the mystical experience say about that?
Separation seems to be a theme that shows up in every spiritual tradition, and the overcoming of it to union is the goal of the seeker.
What is Love? How do we know it? How are we One in it? The mystical experience shows us directly not only what Love is, but that we are Love.
It is perhaps the greatest paradox of all, which the mind will never understand. That is the point.
Can we know anything absolutely? Is there an absolute objective truth out there? What does mysticism say about this?
Is the body an essential part of our true Self? Or is it like a temporary temple for the Divine to live?
What is God's relationship with nature? Is God supernatural or natural? Or both?
