all things consume. We may not experience hunger or self based desire to eat - but we do change.

eating isn't real, it could easily be renamed transformation as all it is - is a changing of one form into another. Energetic transformations are points where 'individuals' come into being. flame, fuel and heat - water, hydrogen and oxygen.

so, if at any point there is a confined and identifiable state, whether that's in some other realm or not - it will have to consume and it will be a center of transformation from one energy into another.
