[129] When this was said, a certain bhikkhu said to the Blessed One: "Venerable sir, what now is aging-and-death (jarāmaraṇa), and for whom is this aging-and-death?" "Not a valid question," the Blessed One said. "Bhikkhu, whether one should say, 'What is aging-and-death, and for whom is this aging-and-death?' or whether one should say, 'Aging-and-death is one thing, and the one for whom there is this aging-and-death is another' — both these assertions are identical in meaning; they differ only in the phrasing. Bhikkhu, when there is the view (diṭṭhi) 'the soul (jīva) and the body are the same,' there is no living of the holy life; and, bhikkhu, when there is the view 'the soul is one thing, the body another,' there is no living of the holy life. Without veering toward either of these two extremes, bhikkhu, the Tathāgata teaches the Dhamma by the middle: 'With birth (jāti) as condition, aging-and-death.'"
