維摩經略疏 7.106

7.106

「即時至維摩詰室」，四、彼佛遣座三萬二千入於方丈，小室能容不迫迮者，住不思議神力故能爾也。即表果報無礙依土。

From "Immediately" up to "Vimalakīrti's room," fourth, that buddha sent thirty-two thousand seats to enter the ten-foot-square room; that the small room could contain them without being cramped was because he abided in inconceivable spiritual power, hence he could do so. This symbolizes the unimpeded dependent land of retribution.
