妙法蓮華經玄義 3.78

3.78

六、明開麁顯妙者，前十六番智，若不決了，但是麁智；若得決了，悉成妙智。何者？如妙莊嚴王，先是外道世智，聞《法華經》便得決了，以邪相入正相，於諸見不動而修三十七品，不捨八邪而入八正，即是決於世智，得入妙智。或與五品齊，或與相似齊，或與分得齊，節節有入，義細作（云云）。

Sixth, clarifying opening the crude and revealing the wonderful: if the previous sixteen sets of wisdom are not resolved, they are merely crude wisdom; if they are resolved, all become wonderful wisdom. How so? For example, King Śubhavyūha was originally a non-Buddhist with mundane wisdom; upon hearing the Lotus Sūtra he attained resolution, entering the correct mark by means of the false mark, cultivating the thirty-seven factors [of enlightenment] without stirring from views, and entering the eightfold noble [path] without abandoning the eight wrong [paths]—this is resolving mundane wisdom to enter wonderful wisdom. It may match the five grades, or match the likeness [stage], or match the partial realization [stage]; each stage has its entry, and the meaning can be elaborated in detail, as explained above.
