on what the Buddha taught
Saṃyutta Nikāya
Vedanāsaṃyuttaṃ
Daṭṭhabbasuttaṃ
SN36.5
'These three, almsmen, feelings. Which three? Feelings with happiness, feelings with suffering, feelings neither with happiness nor with suffering.
Feelings with happiness, almsmen, are to be seen as from suffering, feelings with suffering are to be seen as from a spike, feelings neither with happiness nor with suffering are to be seen as from unstableness.
OK from what, almsmen, to an almsman the feeling with happiness is it is seen from suffering, the feeling with suffering is seen from a spike, the feeling neither with happiness nor with suffering is seen from unstableness. This is called, almsmen, an almsmen rightly seeing. He cut out longing, turned down the yoke, by right comprehension of esteem he made an end of suffering.'
What is happiness he saw from suffering, suffering he saw from a spike,
neither happiness nor suffering being, he saw as from unstableness.
That surely is a rightly seeing almsmen, he understands feelings.
He, the feelings understanding, sees in principle the drainless.
After the breaking up of the body, the principle gained,
the attainer of the highest knowledge can not come to reckoning.
