The mysterious nature of time

[Plenum]

there is something more 'certain' about the physics that you are linking to.  Is it more 'sure' than the exploration of metaphysical ideas and spaces?

However, I am not able to understand the second of your question with respect to the quote-grab above.

I guess it's an interesting point, because the Ra material is a combination of physics and metaphysics.  The 'physics' is more speculative, in the sense of the densities, and the concrete explanation of the energy centres.

That 'physics' is applicable to everyone.  (general).

I guess the metaphysics speaks more to the personal nature of our journey, and how our overall journey takes place, and is shaped.  It tends to be more subjective, and is something that is subject to interpretation. (free will).
