Rādha asks the Buddha about suffering, and the Buddha explains in terms of the five aggregates.At Sāvatthī. Seated to one side, Venerable Rādha said to the Buddha: “Sir, they speak of this thing called ‘suffering’. What is suffering?” “Rādha, form, feeling, perception, choices, and consciousness are suffering. Seeing this … They understand: ‘… there is no return to any state of existence.’”
