說無垢稱經疏 6.451

6.451

經　不住四界（至）遠離三垢。

Sūtra: It does not dwell in the four realms [of earth, water, fire, and wind; it is identical to the realm of space; it is not the six internal sense-bases; it transcends the path of the worldly six sense-faculties; it is unmixed with the three realms;] and is far removed from the three defilements.
