Doesn't seem that new. I go to a meditation group each week where we do body scan + attention on breath, it seems you are putting together different elements that mediators are likely to put together. Communicating that it is mix and match is good but not new -- there are a lot of big words here for a subject which is actually simple and experiential.

I am interesting in meditations you don't find in the literature like the method I use to cut off the mind-body connection over the breath to deal with acute stress. (e.g. attention to the breath is good for a daily habit when things are basically calm, when you are tilted the mind causes chaos in the body and vice versa and that attention makes the problem worse not better.
