For several years I have been convinced that reality for us is a Space, Time, Energy, Mass box since it did not have these aspects, we could not perceive it. This does not mean the "box" is the total essence of REALITY, for REALITY exists beyond what we are able to perceive.
A distinction must be made relative to the "box" and REALITY or you end up with in pantheism. While REALITY is within the "box," the "box" is not REALITY since REALITY transcends the "box." Thus panentheism vs. pantheism.
"To be is to be free, to be choosing, and to be enjoying (slightly or greatly, positively or negatively) the process of selecting from among competing influences. To be doing this is to be alive. To be doing it with the complexity of performing these tasks self-consciously, rationally, purposefully is to be doing it as a person. To have perfect awareness of all this, perfect memory, love, and preservation of it, and to be giving perfect guidance to the others who are involved in the process is to be the only perfect person, God.
"Santiago Sia [in his God in Process Thought, Dordrecht: Martinus Nijhoff Publishers, 1985] summarizes Hartshorne's panentheism:
"Panentheism . . . holds that God includes the world. But it sets itself apart from pantheism in that it does not maintain that God and the world are identical. . . . Hartshorne explains that God is a whole whose whole-properties are distinct from the properties of the constituents. While this is true of every whole, it is more so of God as the supreme whole. . . . The part is distinguishable from the whole although within it. The power of the parts is something suffered by the whole, not enacted by it. The whole has properties too which are not shared by the parts. Similarly, God as whole possesses attributes which are not shared by his creatures. . . . We perpetually create content not only in ourselves but also in God. And this gives significance to our presence in this world." (http://websyte.com/alan/pan.htm)
