Impermanence: rise and fall

the Chachakka Sutta:
“If anyone should say, ‘Feeling is self,’ that is not tenable. For an
arising and a falling away of feeling are discerned. Since its
arising and falling away are discerned, the consequence would
follow: ‘My self arises and falls away.’ Therefore it is not tenable
to say, ‘Feeling is self.’ Thus feeling is non-self” (MN 148/M III
283).
