Looking For a Debate
“Mendicants, take any mendicant who truly understands: ‘This is suffering’ … ‘This is the origin of suffering’ … ‘This is the cessation of suffering’ … ‘This is the practice that leads to the cessation of suffering’. An ascetic or brahmin might come from the east, west, north, or south wanting to debate, seeking a debate, thinking: ‘I’ll refute their doctrine!’ It’s simply impossible for them to legitimately make that mendicant shake or rock or tremble.
