Understanding the processes and principles that underlie mindfulness is a needed step, because this method enters into the armamentarium of empirical clinical psychology. Mindfulness is closely related to several procedures, including acceptance, cognitive defusion, and exposure. Although each of these procedures seems to target different behavioral processes, they are all interrelated, because ultimately all of them target the domination of the literal and evaluative functions of human language and cognition. Because these methods are constructional, not eliminative, their rise may ultimately have a more profound impact on the field than is currently supposed.
