I don't think that's really off-topic & I agree. Another case in point: indigenous Australian cosmology. On the one hand, I don't personally take the notion that ancestors created the landscape very seriously. On the other, this cosmology was part of a system of thought, culture, and action that helped maintain a civilisation's existence for over 40,000 years (a feat we're very clearly not going to match). And such questions naturally address an individual very differently according to their situation. I can't say I'm ever likely to be involved enough with Reiki to need to take a strong stance on its efficacy. So why not just remain open and admit ignorance? That admission seems as hard for humans as does holding an empirical stance. HN is (hardly uniquely) stuffed full of comments proclaiming great certainty about things it's blindingly obvious people hardly know a thing about. It's fine often (and in truth most of the time) just not to know.
