1.30

第五、平復如本，約十行人明如本。此報身無明之病，今病除如本。本修世善之心，無惡業之害、五塵之病，今還復人天善本，修四諦求涅槃。以無見愛，今得前心，故言平復。乃至圓教亦爾，本是法性淨照，起五住妄惑之病，即病除與法性等，故言如本。

Fifth, regarding "restored to their original state": this explains "original state" with reference to the ten types of practitioners. This was the illness of ignorance of the retributive body; now that the illness is removed, it is like the original. Originally, there was the mind of practicing worldly goodness, free from the harms of evil karma and the illnesses of the five dusts; now one returns to the original goodness of humans and devas, practicing the four truths to seek nirvāṇa. Being without the love of views, one now attains that prior mind; hence it is called "restored." Up to and including the round teaching it is also like this: originally there was the pure illumination of the Dharma-nature, and the illness of the deluded afflictions of the five entrenchments arose; now the illness is removed and one is equal to the Dharma-nature; hence it says "like the original."
