[75] But this is possible, Sunakkhatta: some individual person here may be rightly intent on Nibbāna (sammānibbānādhimutto). For an individual person rightly intent on Nibbāna, Sunakkhatta, only talk suited to that finds a footing; he thinks and ponders in accordance with that, he associates with that kind of person, and he finds satisfaction with him. But when talk connected with the base of neither-perception-nor-non-perception (nevasaññānāsaññāyatana) is being spoken, he does not wish to listen, does not lend an ear, does not apply his mind so as to understand, does not associate with that person, and does not find satisfaction with him. Just as, Sunakkhatta, a palm tree with its crown cut off is incapable of growing again, so too, Sunakkhatta, for an individual person rightly intent on Nibbāna, the fetter (saṃyojana) of the base of neither-perception-nor-non-perception has been cut off, cut off at the root, made like a palm stump, obliterated, no longer subject to arising in the future. He should be understood thus: "This individual person, rightly intent on Nibbāna, is detached from the fetter of the base of neither-perception-nor-non-perception."
