Move closer to one of the breathers, and sit down on the floor so that your knees are almost touching theirs. Really try to match the regularity of the breathing of the person directly in front of you. Now reach into the chest of this person. Through the skin that is not theirs, between the bones, and find their heart. Hold it with both hands as you continue to synchronize your breath with theirs.”
