HS,
Even though a 'non-believer' Narkissos, your interpretation of the feelings that might live within yourself, as you described within your post above are a very 'Narkissos' style explanation.
LOL, I wouldn't deny that.
I know it's hard to get this point across (especially across the Atlantic ), but I would rather label myself an "atheist believer" than a "non-believer," which might (?) shed some light on the most obscure narkissisms.
3) They are all cerebral in nature. As you know, stimulating a certain area of the cerebral cortex can give rise to such experiences, visions, and an overwhelming feeling of well-being and of a personal intense love of 'God. Again the interesting thing is that those who have undergone experimentation in this regard all turn to their various Gods for explanation.4) They are cerebral in nature, but the cerebral cortex is stimulated by a supernatural source outside that person.
Perhaps, if you drop the belief in the individual as a self-enclosed monad, there is no real opposition between # 3 and 4. Only the "source" in # 4 doesn't need to be qualified as "supernatural" or exclusively "outside" anymore.
I heartfully agree that all interpretations of such "experiences" are dependent on pre-existent cultural material -- what you happen to have read or have been taught. Ross wouldn't have put the name "Jesus" on it hadn't he read the Bible or be raised in a (generally speaking) Christian environment. I wouldn't relate it to "language" or "symbolism" hadn't I read a few theories about that. I don't think any verbal explanation is better than another objectively -- perhaps because there is no such thing as objective language. What we can do is attempting to translate them from one language to another. The sphere of communication, after all, is the intersubjective, not the objective.
All the best
