It is not the “invisible” truth but the tangible body that changes the truth as the body and mind evolve. The material Spirit Within is the closest thing we can know to the truth about Godhood, because it knows its destination, but even the Spirit is the Will to Godhood, therefore not having attained its destination. Wrestling with truth, although important, is like wrestling with shadows. It is important to know, but more important to be.
We will find the “real” not in truth but in the Object defined by the truth.
