長阿含經 6.p78

6.p78

“There will be a time when 80,000 great cities arise, and the sound of chickens can be heard in the neighboring towns and cities. At that point, a Buddha will arise in the world named Maitreya, who will be a Tathāgata, Arhat, and Completely Awakened One. He’ll perfect the ten epithets just as the present Tathāgata perfected the ten epithets. Among the gods like Śakra, Brahmā, and Māra, demons, gods, ascetics, and priests, or spirits and worldly men, he will be self-realized, as I am self-realized today among those assemblies.
