Well, yes, meditation doesn't fix cancer. But it seems like such an odd point. It's like writing an article to clarify that exercise will not help if your car breaks down. I guess some people have a wrong perception that meditation helps cure cancer, so clarifying that it doesn't is helpful, but that's no real knock against meditation.

IMO, to help you through hard times, the meditation practice needs to be there already. You don't reach for it at the time you have difficulty -- that's probably too late.
