[618] He was dwelling at Sāvatthī. ... "What do you think, Rāhula — is form (rūpa) permanent or impermanent?"
"Impermanent, venerable sir." ...
"Is feeling (vedanā) ... perception (saññā) ... volitional formations (saṅkhārā) ... consciousness (viññāṇa) permanent or impermanent?"
"Impermanent, venerable sir."
"And that which is impermanent — is it suffering (dukkha) or happiness?"
"Suffering, venerable sir."
"And that which is impermanent, suffering, and subject to change — is it fitting to regard it thus: 'This is mine, this I am, this is my self'?"
"Certainly not, venerable sir."
