13.4.p18

Śāriputra said, “Here, wealthy man, a noble disciple serves a noble, cultivates the discipline, and accompanies good friends. From this, they are close to good friends. They don’t observe self as possessing form, and they don’t view self as being in form or that form is in self. They don’t view form as belonging to self or that self belongs to form. That form [deteriorates,] changes, and doesn’t remain. The changing of that form doesn’t give rise to the suffering of sorrow, lamentation, pain, and trouble.
