二、明折愛假以入空者，愛，即是欲愛、色愛、無色愛，皆是四緣、三假之所成也。若觀四緣、三假，入空發真，無礙道斷，解脫道證，至非想第九解脫，是羅漢果住有餘涅槃。折假入空觀，其功乃息。亦名一切智，亦名慧眼。

Second, explaining the analytical reduction of the provisionality of craving to enter emptiness: 'Craving' refers to craving for the desire realm, craving for the form realm, and craving for the formless realm; all are formed from the four conditions and the three provisionalities. If one contemplates the four conditions and three provisionalities, enters emptiness, awakens to the real, severs defilements via the path of non-obstruction, and realizes [cessation] via the path of liberation, up to the ninth liberation of neither-perception-nor-non-perception, this is the fruit of an arhat abiding in nirvāṇa with remainder. Only then does the function of the contemplation of entering emptiness by analytically reducing the provisional come to rest. It is also called the all-knowledge, and also called the wisdom-eye.
