維摩經略疏 2.157

2.157

「於是」下，五、佛現淨土釋疑。文為四：一案地現淨、二問身子、三答、四正釋疑。初文者，亦如上舉日月譬意。地喻真修，指表緣修。真緣若合則真應土現，如指地合故莊嚴土現。

From "Thereupon" onward is the fifth [section], in which the Buddha manifests the pure land to resolve the doubt. The text has four parts: first, pressing his toe to the earth to manifest purity; second, questioning Śāriputra; third, the reply; fourth, directly resolving the doubt. As for the first part: it also has the meaning of the sun and moon simile above. The earth is an analogy for the cultivation of the true; the toe represents the cultivation of the conditional. If the true and conditional unite, the true and response lands appear, just as when the toe and the earth unite, the adorned land appears.
