摩訶止觀 3.230

3.230

又四種皆權。何以故？四理皆不可說。權不可說，故非權；實不可說，故非實。非權而強說為權；非實而強說為實。等是強說，何意不名權為實耶？以有說故，故皆是權。

Moreover, all four kinds are provisional. Why? The four principles are all inexpressible. Because the provisional cannot be expressed, it is not provisional; because the real cannot be expressed, it is not real. What is not provisional is forcibly called provisional; what is not real is forcibly called real. Since both are equally forced expressions, on what grounds would one not call the provisional real? Because there is expression, all are provisional.
