Katamā kathetukamyatāpucchā? bhagavā bhikkhūnaṃ kathetukamyatāya pañhaṃ pucchati "cattārome bhikkhave satipaṭṭhānā, katame cattāro"ti. Ayaṃ kathetukamyatāpucchāti. Tattha buddhānaṃ purimā tisso pucchā natthi, kasmā? buddhānaṃ hi tīsu addhāsu Kiñci saṅkhataṃ addhāvinimuttaṃ vā asaṅkhataṃ adiṭṭhaṃ anaññātaṃ ajotitaṃ atulitaṃ atīritaṃ avibhūtaṃ avibhāvitaṃ nāma natthi, tena tesaṃ adiṭṭhajotanāpucchā natthi. Yaṃ pana bhagavatā attano ñāṇena paṭividdhaṃ, tassa aññena samaṇena vā brāhmaṇena vā devena vā mārena vā brahmunā vā saddhiṃ saṃsandanakiccaṃ natthi, tenassa diṭṭhasaṃsandanā pucchā natthi. Yasmā panesa akathaṃkathī tiṇṇavicikiccho sabbadhammesu vihatasaṃsayo, tenassa vimaticchedanāpucchā natthi. Itarā pana dve pucchā bhagavato atthi. Tāsu ayaṃ "kathetukamyatāpucchā"ti veditabbā.
