I have heard that on one occasion the Blessed One was staying near Vesali , in the Great Forest, at the Gabled Pavilion. Then, in the late afternoon, he left his seclusion and went to the sick ward, where he saw a monk who was weak & sickly. Seeing him, he sat down on a prepared seat. As he was sitting there, he addressed the monks: "When these five things don't leave a monk who is weak & sickly, it can be expected of him that, before long — with the ending of the fermentations — he will enter & remain in the fermentation-free awareness-release & discernment-release, having realized & directly known them for himself in the here & now. Which five?

"There is the case where a monk [1] remains focused on unattractiveness with regard to the body, [2] is percipient of foulness with regard to food, [3] is percipient of distaste with regard to every world, [4] is percipient of the undesirability of all fabrications, and [5] has the perception of death well established within himself.
