I do think it helpful, but I am a huge skeptic of such matters and I didn't arrive where I am now because somebody else told me it was so. Neither would I attempt to persuade others, but I do occasionally offer "things to consider".

My central "offering" at present is that while excellent work is being done in exposing the misdeeds of others, I suspect that little attention is being paid to the nature of our own thoughts and actions. I happen to think that the two are closely related.
