仁王般若經疏 3.171

3.171

The Buddha told King Prasenajit: "I admonish you all: in the eighty years, eight hundred years, and eight thousand years after my parinirvāṇa, there will be no Buddha, no Dharma, no Saṅgha, and no faithful laymen or laywomen. At that time, this sūtra and the Three Jewels are entrusted to the kings and the four groups of disciples, so that they will receive, uphold, read, recite, and explain their meaning, opening the path of empty wisdom for the sentient beings of the three realms, cultivating the practices of the seven worthies, and transforming all sentient beings through the ten good actions."
