三彌勒經疏 1.245

1.245

經曰「滅度之後」以下，第四美佛住持。《大成佛經》云：三像法世三萬歲，及彌勒入涅槃後起塔供養。今此經略故不說。

From the sūtra passage stating, "After his parinirvāṇa," onward is the fourth, extolling the Buddha's preservation [of the Dharma]. The Great Attainment of Buddhahood Sūtra states: the age of semblance dharma lasts for thirty thousand years, and after Maitreya enters nirvāṇa, stūpas are erected to make offerings. Now, because this sūtra is concise, it does not mention them.
