This makes lot of sense to me. In the kind of meditation I'm trying, you are supposed to concentrate on your breath. Instructions usually say that, if you mind wanders, just put attention back on the breath in a non-judgemental way. Don't put yourself down.

What's more, I once read that, when you notice your mind has been wandering, you should be happy because you had a moment of awareness and an opportunity to learn concentration. That's like saying "Huzzah! I caught my mind wandering!"
