Rādha asks the Buddha about what is of impermanent nature, 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 ‘naturally impermanent’. What is naturally impermanent? “Rādha, form, feeling, perception, choices, and consciousness are naturally impermanent. Seeing this … They understand: ‘… there is no return to any state of existence.’”
