觀無量壽佛經疏 4.87

4.87

六、從遇觀世音下，至成羅漢已來，正明第十一門中華開已後得益不同，即有其三。一明逕時已後得遇觀音、大勢。二明既逢二聖得聞妙法。三明逕一小劫已後始悟羅漢也。

Sixth, from "encountering Avalokiteśvara" down to "attains arhatship," it directly clarifies, under the eleventh gateway, the differences in benefits gained after the flower opens. This consists of three points: First, it clarifies encountering Avalokiteśvara and Mahāsthāmaprāpta after time has elapsed. Second, it clarifies hearing the marvelous Dharma upon meeting the two sages. Third, it clarifies awakening to arhatship only after one small kalpa has passed.
