A while ago I was reading through the comments to a post by John Michael Greer, and one of them struck me. You can find the full comment here, from a reader who goes by the sobriquet Northwind Grandma, but the gist of it is as follows:
... Several readers have asked “how can I help during the decline?” Start with one’s intention. If one wants to “help the world,” breathe in the bad and breathe out the good. Close the eyes, and do this twenty minutes a day for the rest of your life.... It is not a meditative practice for the weak. It may sound easy. It is a practice that makes or breaks a world, not to mention what it can do to a person.
It turns out this is a well-known practice in Tibetan Buddhism called tonglen meditation. You can also learn more about it here. Anyway, several people had further comments in the thread—starting with Mr. Greer himself:
Northwind, if that works for you, by all means, but I emphatically don’t recommend this for anyone at all. I know people whose lives went straight down the crapper when they did this, without doing any measurable good for anybody else.
Then there was some additional discussion, for example in this comment here and this one here.
What struck me so hard about this discussion is that I used to do the exact same thing with Wife, or almost. I didn't think of it as a meditation practice, and so I didn't go through all the formal steps that, for example, Pema Chödrön outlines in her article above. In my mind I called it "swallowing bitterness," and I wondered if it might be a practice someone could apply pragmatically in, say, political re-education camps, or perhaps Hell.
