" If we eliminate the recurrence of the causes for suffering, we definitely experience the absence of the suffering that would have arisen as their results. Without a cause, a result cannot arise. Moreover, since the root cause of the recurrence of our problems is the confusion with which we imagine that things actually exist in the impossible manner in which our muddled mind deceptively makes them appear to exist, it is possible to eliminate the recurrence of this cause. This is because confusion cannot be verified. Based on fantasy, not fact, it lacks a stable foundation and cannot withstand close scrutiny. Therefore true endings can definitely occur. In order to realize a true stopping of our problems and their causes, however, we must actively do something to bring it about. Otherwise, due to strong habit, we endlessly continue to make our life miserable — for instance by generating tension over and over again. Since the root cause of our suffering is a confused state of mind, we need to replace it permanently with an unconfused state so that it never arises again. Such unconfused states of mind with which we see reality are the fourth true fact in life — true pathways of mind, or true “paths.” It is not sufficient, therefore, merely to mask over the problem of stress, for example, by taking a tranquilizer or having a drink. We must rid ourselves, or “abandon” the confusion with which we believe that somehow the tension exists “out there.” We must replace confusion "
