Self-critical awareness is essential. Imagination and illusion distort clear observation. Illusion will always exist, so long as the urge for the continuation of pleasure and the avoidance of pain exist; the demand for those experiences which are pleasurable to continue or be remembered; the avoidance of pain, suffering. Both these breed illusion. To wipe away illusion altogether, pleasure and sorrow must be understood, not by control or sublimation, identification or denial.
