摩訶止觀 5.125

5.125

一空一切空，無假中而不空，總空觀也。一假一切假，無空中而不假，總假觀也。一中一切中，無空假而不中，總中觀也。即《中論》所說不可思議一心三觀。歷一切法亦如是。

One emptiness is all emptiness; there is no provisionality or middle that is not empty—this is the total contemplation of emptiness. One provisionality is all provisionality; there is no emptiness or middle that is not provisional—this is the total contemplation of provisionality. One middle is all middle; there is no emptiness or provisionality that is not middle—this is the total contemplation of the middle. This is precisely the inconceivable threefold contemplation in a single thought-moment expounded in the Mūlamadhyamakakārikā. Traversing all phenomena is also like this.
