Yes, and I saw that the author made this point as well. But again, mindfulness isn’t a stress lowering switch, it’s literally training in awareness of what is happening in one’s field of experience which includes a toxic environment if present. Awareness training should NOT render one insulated against your surrounding environment. It should highlight it as you become more aware and attentive.
Now, a LOT of mindfulness programs and teachers ARE essentially selling relaxation practices as mindful attention training, and I would agree that THAT is a problem. But the problem there in my view is not that the practice is being taught without morality or moral principle, but without actual awareness training. It’s relaxation sold as mindfulness. And I think that’s a shame, but I still wouldn’t deny anyone tools to relax. I just wish they wouldn’t call it mindfulness.
