梵網經菩薩戒本疏 1.15

1.15

第二、一頌一句，明此千佛復現百億釋迦。於中，先四句釋一華所現，後一句類結餘華。前中，初句舉一華主百億國。國者，是四天下中南州國也。是故即一三千大千世界有百億四天下等，故云「百億國」。於一一南洲菩提樹下各有一釋迦同時成佛，故云「各坐」等也。類結者，如一華既有百億國，餘九百九十九華亦各主百億，故類結云如是總為千箇百億也。

Second, one verse and one line clarify that these thousand Buddhas further manifest a hundred kotis of Śākyamunis. Therein, first four lines explain what is manifested by one flower, and the latter one line summarizes the remaining flowers by analogy. In the former, the first line brings up that one flower governs a hundred kotis of lands. "Lands" are the southern continent lands among the four continents. Therefore, one three thousand great chiliocosm has a hundred kotis of four continents and so forth; hence it says "a hundred kotis of lands." Under the bodhi tree in each southern continent there is one Śākyamuni simultaneously realizing Buddhahood; hence it says "each sits," and so forth. As for summarizing by analogy: since one flower already has a hundred kotis of lands, the remaining nine hundred and ninety-nine flowers also each govern a hundred kotis; therefore it summarizes by analogy, saying that in this manner they total a thousand hundred kotis.
