The one question that sorts them

Ask it plainly. Has everything gone flat, or only worship?

If your food tastes of nothing, if your children do not reach you, if work is grey and the things you used to look forward to have stopped working, then the flatness is not about religion. Religion is simply one more thing on a long list, and the list is the finding.

If everything else is roughly normal and the flatness is in the prayer mat, that is the state this course is about.

Do this honestly and do it before anything else, because the two need different help and one of them needs it soon.
