[Udayin:] "'Released through discernment, released through discernment,' it is said. To what extent is one described by the Blessed One as released through discernment?"
[Ananda:] "There is the case, my friend, where a monk, withdrawn from sensuality, withdrawn from unskillful qualities, enters & remains in the first jhana: rapture & pleasure born from withdrawal, accompanied by directed thought & evaluation. And he knows it through discernment. It is to this extent that one is described by the Blessed One as released through discernment, though with a sequel.
"Furthermore, with the stilling of directed thoughts & evaluations, he enters & remains in the second jhana... the third jhana... the fourth jhana... the dimension of the infinitude of space... the dimension of the infinitude of consciousness... the dimension of nothingness... the dimension of neither perception nor non-perception. And he knows it through discernment. It is to this extent that one is described by the Blessed One as released through discernment, though with a sequel.
"Furthermore, with the complete transcending of the dimension of neither perception nor non-perception, he enters & remains in the cessation of perception & feeling. And as he sees with discernment, the mental fermentations go to their total end. And he knows it through discernment. It is to this extent that one is described by the Blessed One as released through discernment without a sequel."
