Bhikkhu, ‘I am’ is a conceiving; ‘I am this’ is a conceiving; ‘I shall be’ is a conceiving; ‘I shall not be’ is a conceiving; ‘I shall be possessed of form’ is a conceiving; ‘I shall be formless’ is a conceiving; ‘I shall be percipient’ is a conceiving; ‘I shall be non-percipient’ is a conceiving; ‘I shall be neither-percipient-nor-non-percipient’ is a conceiving. Conceiving is a disease, conceiving is a tumour, conceiving is a dart. By overcoming all conceivings, bhikkhu, one is called a sage at peace. And the sage at peace is not born, does not age, does not die; he is not shaken and does not yearn. For there is nothing present in him by which he might be born. Not being born, how could he age? Not ageing, how could he die? Not dying, how could he be shaken? Not being shaken, why should he yearn?
Then the venerable Pukkusāti, having delighted and rejoiced in the Blessed One’s words, rose from his seat, and after paying homage to the Blessed One, keeping him on his right, he departed in order to search for a bowl and robes. Then, while the venerable Pukkusāti was searching for a bowl and robes, a stray cow killed him.
Then a number of bhikkhus went to the Blessed One, and after paying homage to him, they sat down at one side and told him: “Venerable sir, the clansman Pukkusāti, who was given brief instruction by the Blessed One, has died. What is his destination? What is his future course?”
“Bhikkhus, the clansman Pukkusāti was wise. He practised in accordance with the Dhamma and did not trouble me in the interpretation of the Dhamma. With the destruction of the five lower fetters, the clansman Pukkusāti has reappeared spontaneously in the Pure Abodes and will attain final Nibbāna there without ever returning from that world.”
And we have this alternative translation of the relevant passage from Bhikkhu Sujato:
"But while he was wandering in search of a bowl and robes, a stray cow took his life.
Then several mendicants went up to the Buddha, bowed, sat down to one side, and said to him, “Sir, the gentleman named Pukkusāti, who was advised in brief by the Buddha, has passed away. Where has he been reborn in his next life?”
“Mendicants, Pukkusāti was astute. He practiced in line with the teachings, and did not trouble me about the teachings. With the ending of the five lower fetters, he’s been reborn spontaneously and will become extinguished there, not liable to return from that world.”
What did the Buddha mean in MN 140 about what happened to clansman Pukkusāti after a cow killed him?
