Then the Blessed One said…”What is the Noble Truth of Suffering? Birth is suffering, death is suffering, sorrow, lamentation, pain, sadness and distress are suffering. Being attached to the unloved is suffering, being separated from the loved is suffering, not getting what one wants is suffering…, the five aggregates of grasping are suffering.
….what is not getting what one wants? In beings subject to birth this wish arises ‘Oh that we were not subject to birth, that we might not come to birth!’ but this cannot be gained by wishing. That is not getting what one wants. In being subject to ageing, disease, to death, to sorrow, lamentation, pain, sadness and distress this wish arises ‘Oh that we…might not come to these things!’ But this cannot be gained by wishing. That is not getting what one wants.
What is the Noble Truth of the Origin of Suffering? It is that craving which gives rise to rebirth, bound up with pleasure and lust, finding fresh delight now here, now there: that is to say sensual craving, craving for existence, and craving for non-existence.
Wherever in the world there is anything agreeable and pleasurable, there this craving arises and establishes itself.
What is the Noble Truth of the Cessation of Suffering? It is the complete fading away and extinction of this craving, its forsaking and abandonment, liberation from it, detachment from it. How does this craving come to be abandoned, how does its cessation come about?
What is the Noble Truth of the Way of Practice Leading to the Cessation of Suffering?
It is the Noble Eight-fold Path, namely: Right View; Right Thought; Right Speech; Right Action; Right Livelihood; Right Effort; Right Mindfulness; Right Concentration.
There is this one way to the purification of beings, for the overcoming of sorrow and distress, for the disappearance of pain and sadness, for the gaining of the right path, for the realization of Nibbana: that is to say the four foundations of mindfulness” and it is for this reason that it was said.”
-Buddha, Mahasatipatthana Sutta
