Completeness is the key word. "Am" begs the question who and "I" inherently "am". "I am" is then inherently complete, perfect. In human terms it's bliss or love. What you call rational, I would call causal, natural, or making perfect sense to my rational mind. It's the reflection of completeness onto human form. Therefore you always have to look at reason to see Absolute. The completeness you directly see is not the completeness that really is (as it is).

I'll tackle the rest in a reply to your linked piece.
