I don't know if your et al too includes me, TBPL, but the truth is that even amongst the people I know whose understanding of spiritual energy is similar to mine (everybody's different, so I won't say "the same"), no one experiences it even a little bit the way I do. This is not because I have any special "powers", but only because I have certain deficiencies that cause this kind of energy to get a bit blocked and I get easily overloaded. I've never met anyone else who throws up when they are exposed to high concentrations of spiritual energy. And I wish it didn't happen to me either, because it's quite unpleasant.

As far as other people's ability to percieve spiritual energy, again it's not a power. It's simply an ability. I think everyone has this ability but, for reasons of their own, many people are just not prepared to use it.

From my own perspective, as far as proof is concerned, I would not seek to prove anything of a spiritual nature to anyone. I see that sort of thing as a violation of the free will of another and, to my way of thinking, intrusive and counterproductive. But by the same token, I don't think it would be particularly productive for me to pretend that I experience or understand things any differently than I do.
