"Be aware of your breathing. Notice the sensation of the breath. Feel the air moving in and out of your body. Notice how the chest and abdomen expand and contract slightly with the in and out breath. One conscious breath is enough to make some space where before there was the uninterrupted succession of one thought after another. One conscious breath (two or three would be even better), taken many times a day, is an excellent way of bringing space into your life."
