sn12.17:4.1 “Worthy Gotama, when asked these questions, you say ‘not so’.

sn12.17:4.5 Yet you say that there is such a thing as suffering.

sn12.17:4.7 And you say that you do know suffering,

sn12.17:4.8 and you do see suffering.

sn12.17:4.9 Sir, let the Blessed One explain suffering to me!

sn12.17:4.10 Let the Blessed One teach me about suffering!”
