維摩經略疏 2.21

2.21

問：合蓋現土何得知表報應身土？答：五百小蓋合成其一，豈非表眾因合成一果？一果者即是圓報法身，身即有土，故文中菩薩修檀等行成佛之時，如是眾生來生其國。

Question: Uniting the parasols and displaying the lands—how is it known to indicate the retribution and response bodies and lands? Answer: Five hundred small parasols unite into a single one; how could this not indicate the convergence of myriad causes into a single fruit? The single fruit is precisely the complete retribution dharmakāya; where there is a body there is a land. Therefore, in the text, when the bodhisattva cultivates practices such as dāna and achieves buddhahood, such sentient beings come to be born in that land.
