My suspicion is that duality and nonduality are mortal created concepts that are not a part of our truth.

I also suspect that we are other than spirit or even energy in our true form within the Mind of God.

Thought would be the closest thing that I can envision our true essence being. And if there is one mind thinking all of us the mortal idea of duality and nonduality would be a moot point.

This is why to know our true selves we must acknowledge a creator. It is God's Mind that contains all of His Thoughts which we are and which He knows unitedly as His Son.

Our true power cannot be expressed individually unless we are cognizant of relationship with the Father/Creator/Mind of God. And then it is only manifest because we access fully the oneness of All That Is which is what Jesus and a few others ((thinking of Yogananda ) accessed.
