The Discourse on the Sick
121.
On one occasion the Blessed One was dwelling at Vesālī in the Great Wood in the Pinnacled Hall.
Then the Blessed One, in the evening, having emerged from seclusion, went to the hall for the sick .
The Blessed One saw a certain monk who was a frail and sick;
having seen him, he sat down on the prepared seat.
Having sat down, the Blessed One addressed the monks:
"Monks, if five qualities do not leave a frail and sick monk, it can be expected of him: 'In no long time, through the elimination of the mental corruptions, he will realise for himself, with direct knowledge, in this very life, the liberation of mind and liberation by wisdom that are free from mental corruptions, and, having entered upon them, he will dwell in them.'"
Which five? Here, monks, a monk dwells observing foulness in the body, perceiving repulsiveness in food, perceiving discontent in the whole world, observing impermanence in all activities, and the perception of death is well established internally for him. Monks, if these five qualities do not leave a frail and sick monk, it may be expected of him: 'In no long time, through the elimination of the mental corruptions, ... he will realise for himself, ... and, having entered upon them, he will dwell in them.'" The first.
