摩訶止觀 4.113

4.113

閑寺一房者，即從假入空觀也。寺本眾鬧居處，而能安靜一室；假是囂塵，能即假而空，當知真諦亦是處也。

A single room in a quiet temple is the contemplation of entering emptiness from the provisional. A temple is originally a crowded dwelling place, yet one is able to be peaceful and quiet in a single room; the provisional is clamor and dust, yet one can realize emptiness right within the provisional. One should know that the true truth is also such a place.
