XXXI The Buddha’s Parents Attain Nirvāna
When Suddhodana had grown old, he fell sick and sent for his son to come and see him once more before he died; and the Blessed One came and stayed at the sick-bed, and Suddhodana, having attained perfect enlightenment, died in the arms of the Blessed One. 1
And it is said that the Blessed One, for the sake of preaching to his mother Māyā-devī, ascended to heaven and dwelt with the devas. Having concluded his pious mission, he returned to the earth and went about again, converting those who listened to his teachings. 2
