There's an issue with the current rise of popularity of the practice. Many generally non-mindful entities and persons are trying to cash out on the concept and they are adding a lot of new-agy noise.
I've discovered helpful practices through some of these new-agey sources. I think as long as the consumers don't get trapped under dogma, hero-worship or financial burdens and do their own due-diligence then I'm fine with these new players.
It may not be "right" that they are raking in the money for centuries-old practices but that's the way it is with capitalism.
Same here but I spent a lot of time to understand where to look. Thanks to Headspace, it made things much easier.
I'm not against earning money for teaching and the world needs more mindful people anyway. The problem for me is that most of these sources are very egocentric and focused on personal well-being when the centuries-old practices are deeply philosophical and also teach compassion and loving kindness.
I'm not sure popularization of the practice of mindfulness is anything very new. E.g., Alan Watts made a big name for himself doing this back in 1950's and before, and est was a big thing in the 1970's (https://en.wikipedia.org/wiki/Erhard_Seminars_Training ) It's been around as a major cultural thing since then and before.
In any case, it seems to me that even more "scientific" subjects, like, say diet or exercise science, have similar levels of "faddiness". It can be hard to separate the legitimate from the merely titillating.
