I have learned this in the presence of the Buddha: ‘When the being intent on awakening emerges from his mother’s womb, then—in this world with its gods, Māras, and divinities, this population with its ascetics and brahmins, gods and humans—an immeasurable, magnificent light appears, surpassing the glory of the gods. Even in the boundless gloom of interstellar space—so utterly dark that even the luminosity of the moon and the sun, so mighty and powerful, makes no impression—an immeasurable, magnificent light appears, surpassing the glory of the gods. And the sentient beings reborn there recognize each other by that light: “So, it seems other sentient beings have been reborn here!” And this ten-thousandfold galaxy shakes and rocks and trembles. And an immeasurable, magnificent light appears in the world, surpassing the glory of the gods.’ This too I remember as an incredible and amazing quality of the Buddha.”
“Well then, Ānanda, you should also remember this as an incredible and amazing quality of the Realized One. It’s that the Realized One knows feelings as they arise, as they remain, and as they go away. He knows perceptions as they arise, as they remain, and as they go away. He knows thoughts as they arise, as they remain, and as they go away. This too you should remember as an incredible and amazing quality of the Realized One.”
“Sir, the Buddha knows feelings as they arise, as they remain, and as they go away. He knows perceptions as they arise, as they remain, and as they go away. He knows thoughts as they arise, as they remain, and as they go away. This too I remember as an incredible and amazing quality of the Buddha.” That is what Venerable Ānanda said, and the Teacher concurred. Satisfied, those mendicants approved what Venerable Ānanda said.
