Working your way through the body, you’ll eventually reach areas where you can readily observe changes in sensations that clearly correspond to the breath cycle. These will almost certainly include the upper back, chest, and abdomen, and possibly the lower back, shoulders, and upper arms as well. These breath-related sensations are comparatively gross, produced by changes in pressure and body parts moving against clothing or each other. Eventually, however, you’ll be able to detect very subtle changes related to the breath in every part of the body.
