"You can use even your elbow. For instance, if you're standing behind someone sitting in a chair, put your elbow on the shoulder muscle, where there is always a lot of tension. Lean gently, very slowly, applying pressure for three or four breaths. Then move your elbow an inch or two away and put pressure in the next area.

You want a seven or an eight. Most important is: 'Does this feel good?' Ask again and again, and adjust your technique accordingly."
