What is the noble truth of suffering? It is the suffering of birth, the suffering of old age, the suffering of sickness, the suffering of death, the suffering of separation from loved ones, the suffering of facing unwanted phenomena, and the suffering of not getting what one is seeking. In brief, every aspect of the five aggregates is suffering.
What is the noble truth of the source of suffering? It is craving [which produces] re-existence [as a being in samsara], and which is accompanied by passionate desire, and which is total delight with [or attachment to] this and that.
What is the noble truth of the cessation of suffering? It is the total abandonment, renunciation, purification and exhaustion of the craving [which produces] the re-existence, and which is accompanied by passionate desire, and which is total delight in this and that. It is the complete freedom from, cessation of, pacification of and termination of desire.
What is the path that leads to the cessation of suffering? It is the Noble Eightfold Path, which consists of right view, right thought, right speech, right action, right livelihood, right effort, right mindfulness and right contemplation.
