Our sitting instructions state, “sit as quietly as you can,” but perfect silence during meditation is neither necessary nor possible. Listening to sound without running away from it, or chasing after it, is actually an important part of our basic practice (“Listening to Survive”). If, however, you happen to be looking for some real peace and quiet, you might study a new map that scientists have constructed of noise levels on an “average summer day.” The quietest (deep blue) regions include parts of Yellowstone National Park (Wyoming) and the Great Sand Dunes National Park (Colorado).
