View the sensation as limited in time, changeable, and transient, or “contemplate impermanence.” (“This sensation only peaks for a few seconds at a time and then fades away; it will probably be gone in a couple of days.”) If you have an acute problem like toothache, you’ll have forgotten what it felt like years from now. If you have a long-term problem such as chronic sciatica, you’ll know it sometimes gets worse and so at other times it must be less severe. It makes a difference if you can focus on the notion that this shall pass.
