One specific method of practicing mindfulness of body sensations is to focus your attention on sounds. . . .

Don't scan for sounds; wait for them. You might think of the difference between radar that goes out looking for something and a satellite dish with a wide range of pickup capacity that just sits in the backyard, waiting. Be a satellite dish. Stay turned on, but just wait.
