[279] "Regarding this, Poṭṭhapāda, those ascetics and brahmins who say, 'A person's perceptions (saññā) arise and also cease without cause, without condition' — they are wrong from the very start. Why is that? Because, Poṭṭhapāda, a person's perceptions arise and also cease with cause, with condition. Through training (sikkhā) one perception arises; through training one perception ceases. And what is that training?" said the Blessed One. "Here, Poṭṭhapāda, a Tathāgata arises in the world, an Arahant, a Fully Self-Awakened One … (to be expanded as in the Sāmaññaphala). Thus indeed, Poṭṭhapāda, a bhikkhu is accomplished in virtue … When he sees that these five hindrances (nīvaraṇa) have been abandoned in himself, gladness is born; in one who is gladdened, rapture (pīti) is born; when the mind is filled with rapture, the body becomes tranquil; one whose body is tranquil feels happiness; in one who is happy the mind (citta) becomes concentrated. Quite secluded from sensual pleasures, secluded from unwholesome states, he enters upon and dwells in the first jhāna, which is accompanied by thought and examination, with rapture and happiness born of seclusion. His former perception of sensuality ceases; on that occasion there is a subtle and true perception of the rapture and happiness born of seclusion; on that occasion he is percipient precisely of the subtle and true rapture and happiness born of seclusion. Thus too, through training one perception arises; through training one perception ceases. And this is that training," said the Blessed One.
