[66] 1. Thus have I heard. On one occasion the Blessed One was dwelling at Sāvatthī, in the Jetavana, Anāthapiṇḍika's Park. Now on that occasion a certain bhikkhu was seated not far from the Blessed One, having folded his legs crosswise and set his body erect, enduring a painful (dukkha), sharp, bitter feeling (vedanā) born of the ripening of old kamma (purāṇakammavipākaja) — mindful (sato), clearly comprehending (sampajāno), without being distressed.
The Blessed One saw that bhikkhu seated not far away, having folded his legs crosswise and set his body erect, enduring a painful, sharp, bitter feeling born of the ripening of old kamma — mindful, clearly comprehending, without being distressed.
Then the Blessed One, having understood this matter, on that occasion uttered this inspired utterance (udāna):
For the bhikkhu who has abandoned all kamma,
shaking off the dust that was made before,
without 'mine,' steadfast, such a one —
there is no need to speak to people.
The first sutta.
