The Long Āgama Sūtra 6.27

6.27

「八萬歲時人，女年五百歲始出行嫁。時，人當有九種病，一者寒，二者熱，三者飢，四者渴，五者大便，六者小便，七者欲，八者饕餮，九者老。時，此大地坦然平整，無有溝坑、丘墟、荊棘，亦無蚊、虻、蛇、蚖、毒蟲，瓦石、沙礫變成琉璃，人民熾盛，五穀平賤，豐樂無極。是時，當起八萬大城，村城隣比，雞鳴相聞。當於爾時，有佛出世，名為彌勒如來、至真、等正覺，十號具足，如今如來十號具足，彼於諸天、釋、梵、魔、若魔、天、諸沙門、婆羅門、諸天、世人中，自身作證，亦如我今於諸天、釋、梵、魔、若魔、天、沙門、婆羅門、諸天、世人中，自身作證。彼當說法，初言亦善，中下亦善，義味具足，淨修梵行，如我今日說法，上中下言，皆悉真正，義味具足，梵行清淨。彼眾弟子有無數千萬，如我今日弟子數百。彼時，人民稱其弟子號曰慈子，如我弟子號曰釋子。

“When they lived for 80,000 years, women would go out to be married starting at 500 years of age. During that time, people had nine types of illness: 1. chills, 2. fevers, 3. hunger, 4. thirst, 5. defecation, 6. urination, 7. desire, 8. greed, and 9. old age. The Earth was relaxing and level. There weren’t any ditches, wastelands, or brambles. Nor were there biting insects, snakes, or other poisonous creatures. Clay, stone, sand, and rocks changed into agate, the people were prosperous, and the five crops were consistently bountiful without end.

“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.

“He will teach the Dharma that’s good in the beginning and good in the middle and end. It’ll be complete in content and expression and purify the religious practice. His assembly of disciples will have countless hundreds of thousands just as my disciples today number in the hundreds. The populace will call his disciples ‘sons of Maitreya’ in the same way my disciples are as known as ‘sons of the Śākya.’
