妙法蓮華經玄義 4.101

4.101

又圓三三昧圓破二十五有：即空故，破二十五惡業見思等；即假故，破二十五無知；即中故，破二十五無明。即一而三，即三而一。一空一切空，一假一切假，一中一切中，故名如來行。

Furthermore, the perfect three samādhis perfectly destroy the twenty-five realms of existence: being identical to emptiness, they destroy the twenty-five evil karmas, view and thought afflictions, and so forth; being identical to the provisional, they destroy the twenty-five kinds of ignorance [regarding dust and sand]; being identical to the middle, they destroy the twenty-five kinds of fundamental ignorance. Identical to one yet three, identical to three yet one. When one is empty, all are empty; when one is provisional, all are provisional; when one is middle, all are middle; therefore it is called the Tathāgata's practice.
