Mahāparinibbāna Sutta 3.40.7

3.40.7

‘tiṭṭhatu, bhante, bhagavā kappaṃ, tiṭṭhatu sugato kappaṃ bahujanahitāya bahujanasukhāya lokānukampāya atthāya hitāya sukhāya devamanussānan’ti.

'Hast thou faith, Ânanda?'
'Even so, Lord!'
'Then, O Ânanda, thine is the fault, thine is the offence-in that when a suggestion so evident and a hint so clear were thus given thee by the Tathâgata, thou wast yet incapable of comprehending them, and thou besoughtest not the Tathâgata, saying, "Vouchsafe, Lord, to remain during the kalpa. Live on, O Blessed One! through the kalpa for the good and the happiness of the great multitudes, out of pity for the world, for the good and the gain and the weal of gods and men." If thou shouldst then have so besought the Tathâgata, the Tathâgata might have rejected the appeal even to the second time, but the third time he would have granted it. Thine, therefore, O Ânanda, is the fault, thine is the offence!'
