The four noble truths are the truths of 
    dukkha—suffering and    stress—its origination, its cessation, and the path to its    cessation. The framework of these noble truths derives from the    fact that there are two kinds of desires, unskillful—the forms    of craving leading to suffering—and skillful, the forms of    desire that give guidance to the path in the form of right    resolve and right effort. Skillful desires find expression in    terms of appropriate attention (right view) and intention (the    practices of right speech, right action, right livelihood,    right effort, right mindfulness, and right concentration). Of    these factors, the Buddha gave prominence to right view. Unlike    the first and second knowledges—which were expressed in terms    of becoming, i.e., beings and worlds—right view on the level of    the third knowledge dropped those terms, regarding experience    in terms of events immediately present to awareness.
“Now this, monks, is the noble truth of stress: Birth is  stressful, aging is stressful, death is stressful; sorrow,  lamentation, pain, distress, & despair are stressful; association  with the unbeloved is stressful, separation from the loved is  stressful, not getting what is wanted is stressful. In short, the  five clinging-aggregates are stressful.
 
“And this, monks, is the noble truth of the origination of  stress: the craving that makes for further-becoming—accompanied  by passion & delight, relishing now here & now there—i.e.,  craving for sensuality, craving for becoming, craving for  non-becoming.
“And this, monks, is the noble truth of the cessation of  stress: the remainderless fading & cessation, renunciation,  relinquishment, release, & letting go of that very craving.
 
“And this, monks, is the noble truth of the way of practice  leading to the cessation of stress: precisely this noble  eightfold path—right view, right resolve, right speech, right  action, right livelihood, right effort, right mindfulness, right  concentration.” —
