摩訶止觀 3.122

3.122

二乘體假入真，秖入但空，不能從但空入假，無化他之用。菩薩體假入但真，能從但空入假，化度眾生，淨佛國土。上根菩薩體假入真，前入但空，次入不但空，則破無明，見佛性，與前真永別，豈可同為一真諦耶？

The two vehicles embody the provisional to enter the ultimate, but they enter only mere emptiness and cannot enter the provisional from mere emptiness, lacking the function of transforming others. Bodhisattvas embody the provisional to enter the mere ultimate, and are able to enter the provisional from mere emptiness, transforming and delivering sentient beings and purifying Buddha-lands. Bodhisattvas of superior faculties embody the provisional to enter the ultimate: first they enter mere emptiness, and next they enter not-mere-emptiness; they then shatter avidyā and perceive Buddha-nature, which is utterly distinct from the previous ultimate. How could they be the same single ultimate truth?
