RE" "Is God part of reality or outside reality?"

There are two other options:

However, I think you are exploiting an ambiguity with the word "reality". If "reality" refers just to the physical or natural universe instead of the natural+supernatural totality, the antecedents of your conditional (if-then) propositions would both be false and the ironical consequents couldn't be concluded.

A panentheistic god couldn't be a mere part of something that is a mere part of him, nor could a pantheistic god be a mere part of himself.

In my view, God is a reality, However, much clarity is needed to understand 'who is God' or 'what is God'. How did we get the taste in our tongue; or, from where the emotions landed up within us. Can we figure that out? Seemingly, we just take it for granted that these are automatic, being a homo sapien. Interestingly, animals too (or, even plants) express their feelings. Where did this power come from needs to be examined

I think that you need to carefully define reality in order to be able to answer this question. There is purely materialistic reality, but taking that approach runs into numerous problems even without invoking God. Simple human consciousness defies explanation in tis limited reality. Electromagnetic waves impact on nerve receptors and are transformed into distinguishable colors or meaningful sounds in just two of the many possible cases, yet color and meaningful sound does not fit within a purely physical reality as these phenomena do not appear to be purely physical.

However, as soon as we expand this purely physical reality to include these phenomena we encounter the problem of, how do we logically limit this expanded reality? What phenomena lie within an expanded reality and which do not, and how to we distinguish with any objective basis? Are NDE accounts, which are remarkably consistent across both time and culture, admissible? And if they are, what do we do with the consistent descriptions of some entity that appears to be all loving? And since that entity appears to be separate from other entities, what does that do to both pantheism and panentheism? And please note that even this does not begin to deal with the question of, is the encountered entity always the same or are there multiple entities that fit this all loving description?
