Consider one symptom of the malady of modern life: people who live the most privileged lives, who have abundant wealth, good health, loving family and friends, can be prey nonetheless to a chronic low-grade dissatisfaction in the midst of this abundance. The richest banquet, the most exotic travel, the most interesting, attractive lover, the finest home — all of these experiences can seem somehow unrewarding and empty if we don't really attend to them fully — if our minds are elsewhere, preoccupied with disturbing thoughts.
