三彌勒經疏 1.190

1.190

經曰「爾時眾中」以下，第三時眾得益。姟者數名，謂《佛本行集經》言「百百千為千萬，千萬百為十億，十億百為千億，千億百為萬億，萬億百為千萬億，千萬億百為十兆，十兆百為千兆，千兆百為十萬兆，十萬兆百為十京，十京百為千京，千京百為十萬京，十萬京百名為姟」也。前九十六億等，顯三會得阿羅漢人等。今云姟者，三會得初果人等也。

From the sūtra's words, "At that time, among the assembly..." onward is the third [section], on the assembly of the time gaining benefit. "*Gai*" (姟) is the name of a number. That is to say, the *Abhiniṣkramaṇasūtra* (*Bensheng ji jing*) states: "One hundred times one hundred thousand is a ten-million (*koṭi*); one hundred times a ten-million is ten hundred-millions (*arbuda*); one hundred times ten hundred-millions is a thousand hundred-millions; one hundred times a thousand hundred-millions is ten thousand hundred-millions; one hundred times ten thousand hundred-millions is a hundred thousand hundred-millions; one hundred times a hundred thousand hundred-millions is ten trillion; one hundred times ten trillion is a thousand trillion; one hundred times a thousand trillion is one hundred thousand trillion; one hundred times one hundred thousand trillion is ten quadrillion; one hundred times ten quadrillion is a thousand quadrillion; one hundred times a thousand quadrillion is one hundred thousand quadrillion; one hundred times one hundred thousand quadrillion is called a *gai*." The ninety-six hundred million and so forth mentioned earlier indicate those who attain the state of an arhat across the three assemblies. What is now called a *gai* indicates those who attain the first fruition [stream-enterer] and so on across the three assemblies.
