In this way, by a visible cause such as medicine, there is no remedy for bodily internal suffering with certainty, that is, inevitably, [or] with finality, that is, entirely. Likewise, even for mental [suffering], there is sometimes no cessation even from contact with pleasant sounds and the like. Likewise, material [suffering] also sometimes departs by means, and sometimes not. Likewise, supernatural [suffering] also sometimes departs, and sometimes not. Moreover, even the departure of suffering is useless because it arises again. But for this student, a cause for the departure of suffering that is certain and final is desired. Therefore, it is appropriate to approach a teacher for that sake. // 1
