One does wonder. Still, a case can be made that the physical laws themselves are "spiritual entities" in the sense that they are not concrete existents themselves, but have governance over all concrete existences.
I ain't gonna pray to the speed of light.
Well then we will be sounding like Hindus. I believe that spiritual laws supercede physical, even in the realm of metaphysics. "Karma" for example, is a physical law. Grace is the spiritual law
Perhaps we can agree on something like "insight" being an aspect of intelligent life. Just as a mathematician experiences those moments of clarity and might wonder whether the source of them is internal or external, he knows that they are real and can lead to Truth. Surely we can agree that such awareness is not ordinary and we commonly call it a gift. So too do we experience spiritual insights with the gift of the Holy Spirit. Maybe this gives us some commonality -- experiencing the here and now on a completely different level than just existing.
