Reddit reviews Anxious: Using the Brain to Understand and Treat Fear and Anxiety

Ledoux briefly talks about it in his recent book Anxious. Basically he thinks these type of meditative or practices which focus you on the here and now can be used for anxiety because they pretty much just hijack attention away from aimless self reflective thought (anxious worry) into the momentary flow of controlling the movement of the body (whether its a breathing exercise or whatever), but I think he even questions there whether it is capable of spilling over beyond that event into daily life, and I think he suspect it could have a kind of self soothing effect where the practitioner learns attunement to their body as a means of suppressing and regulating worry and anxiety in response to events. Look at his book the next time you are in the book store, he has several pages devoted to talking about it.
