The breath is not something that we create or imagine; it is a natural process of our bodies that continues as long as life lasts, whether we concentrate on it or not. So it is an object that is always present; we can turn to it at any time. We don’t have to have any qualifications to watch our breath. We do not even need to be particularly intelligent — all we have to do is to be content with, and aware of, one inhalation and exhalation.
Wisdom does not come from studying great theories and philosophies, but from observing the ordinary.
