I've also seen it make some people more likely to fall into the trap of woo-science and dodgy, spiritual scams. The practice of awakening forces you to investigate the ways you suffer. Before, they may throw their money at these sketchy MLMs and still suffer. With meditation, they can throw their money at them and also suffer a lot less.
Your comments on the nature of this phenomenon are insightful.
If you are not trying to do zazen off the cushion you aren't putting in right effort. You should be aiming to manifest non-discriminating mind at all times
I don’t think this means you dont feel sad or angry or even jealous or anything else. It means, when you’re sad, just be sad. Don’t be too sad about being sad.. :)
As for the other stuff, it's about not identifying with your thoughts. Sad thoughts can still arise, you just don't grab it and say "that's me"
