on what the Buddha taught
Saṃyutta Nikāya
Vedanāsaṃyuttaṃ
Daṭṭhabbasuttaṃ
SN36.5
'These three, almsmen, feelings. Which three? Feelings of happiness, feelings of suffering, feelings of neither happiness nor suffering.
Feelings of happiness, almsmen, are to be seen as from suffering, feelings of suffering are to be seen as from a spike, feelings of neither happiness nor suffering are to be seen as from unstableness.
OK from what, almsmen, to an almsman the feeling of happiness is it is seen from suffering, the feeling of suffering is seen from a spike, the feeling of neither happiness nor 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.
