Some things being above reason

[Neo-Scholastic]

...there are obviously altered states to our usual consciousness...But I don't think any of them trump all others.

Yes mystical/visionary states are only one part of the overall human experience. They do all contribute to the overall health and well being of the person, e. g. if you don't get enough sleep it affects you mood. Sleep or wakefulness are both necessity. One can oversleep. One can stay awake too late. Visionary states profoundly affect those who have them but they are rare and apparently not everyone is fortunate enough to have experienced them. I find that very sad.

Don't forget that you never escape being an electro-chemical being with emotional and feeling states as well as cognitive ones...

I would dispute, on both experiential and philosophical grounds that physical reduction does not capture the fullness of what it means to be human.

...all you have now is your remembrance of the event - and that isn't the same thing at all.

Nor do we remember dreams with the salience they had while we slept, but they can contribute to our waking lives even as our waking lives intrude into our dreams.
