4.22

初、正判四空。滅色入空者，三藏教也。且寄色言諸法皆滅，謂析破見愛，陰乃不生。既詮實有，滅方入空也。即色是空者，通教也。體乎因果非四性生，既詮幻有，故即色是空也。滅邊入空者，別教也。中道為空，不唯空有亦乃空空，然不知中具於空有，是故次第滅二邊已，方入中空也。即邊是空者，圓教也。中道具德，何邊不中？唯假唯空三皆絕待，頓破諸相，名即邊空。

First, properly judging the four emptinesses. Extinguishing form to enter emptiness is the Tripiṭaka teaching. Form is provisionally mentioned, yet all dharmas are extinguished; this means that when view and craving are analyzed and destroyed, the aggregates will not arise. Since it explicates real existence, only upon extinguishing does one enter emptiness. Form itself being emptiness is the Shared teaching. One embodies causes and effects as not arising from the four natures; since it explicates illusory existence, form itself is emptiness. Extinguishing the extremes to enter emptiness is the Distinct teaching. The Middle Way is emptiness; it not only empties existence but also empties emptiness. Yet it does not know that the Middle embodies both emptiness and existence; therefore, only after sequentially extinguishing the two extremes does one enter the Middle emptiness. The extremes themselves being emptiness is the Complete teaching. The Middle Way is endowed with virtues; what extreme is not the Middle? Solely provisional and solely empty, all three are mutually absolute; immediately breaking through all characteristics, it is called the emptiness wherein the extremes themselves are emptiness.
