Digha Nikaya 1:522
SUJATO‘na tāvāhaṁ, pāpima, parinibbāyissāmi, yāva me idaṁ brahmacariyaṁ na iddhañceva bhavissati phītañca vitthārikaṁ bāhujaññaṁ puthubhūtaṁ yāva devamanussehi suppakāsitan’ti.
‘Wicked One, I will not be fully extinguished until my spiritual path is successful and prosperous, extensive, popular, widespread, and well proclaimed wherever there are gods and humans.’
