Highly recommend most of us to try gluten free diet at least for a couple of days! (No wheat, rye or, Lawd have mercy, barley!?)
It's way weird but after I've been on that diet for a couple of weeks now, also the "other" saMyama-s (not just YF) seem to have some effect, or stuff! Well, mainly that's prolly due to my being able to concentrate ("do" dhaaraNaa*) better, because the constant irritation of my lungs has diminished, I'd say at least by 90 percent! *saMyamaH = dhaaraNaa "+" dhyaanam "+" samaadhiH (trayam [(those) three] ekatra: saMyamaH)
