Liable to Suffering
At Sāvatthī. Seated to one side, Venerable Rādha said to the Buddha: “Sir, they speak of having ‘suffering nature’. What is of a nature to suffer?” “Rādha, form, feeling, perception, choices, and consciousness are of a nature to suffer. Seeing this … They understand: ‘… there is nothing further for this place.’”
