妙法蓮華經玄義 4.48

4.48

此地具足四德：破二十五有煩惱名淨；破二十五有業名我；不受二十五有報名樂；無二十五有生死名常。常、樂、我、淨，名為佛性顯，即此意也。

This ground is fully endowed with the four virtues: shattering the afflictions of the twenty-five states of existence is called purity; shattering the karma of the twenty-five states of existence is called self; not receiving the retributions of the twenty-five states of existence is called bliss; and being without the birth-and-death of the twenty-five states of existence is called permanence. Permanence, bliss, self, and purity are called the manifestation of buddha-nature; this is its meaning.
