There are no further possibilities.

D) All reality and existence is consciousness.

Since all-consciousness is all-power...
Soul, matter, or anything else is then simply a particular status, poise, or projection of consciousness-force within the All, whether static or dynamic.

To call matter a "substance" is imposing a material construct or paradigm on the larger scheme, and why then "connection between" becomes result and necessity of that reasoning.

Matter is really a very limited consciousness, a conditional ignorance of what is native to the soul-consciousness that is infinitely more aware and has free access to a comprehensively greater reality within that awareness. But they both originate in and are the same in essence. This is not "dualism", because there is in fact, no "connection" - they are One. The soul is therefore not "supernatural", but rather simply extraordinarily Natural.

When our instrumental consciousness ascends or surrenders to that of the soul, we become that which it inalienably and eternally is.
