摩訶止觀 6.32

6.32

今若取釋義便者，約十度明義，以第六般若入空之慧斷惑盡，與羅漢齊；第七方便般若出假化用，此名目為便。若取七地齊羅漢，約諸地對果向，七地正與第四果齊。此皆一往相主對，經論不定，復須斟酌，不可苟執云云。

Now, if one takes what is convenient for explaining the meaning: explaining the meaning in terms of the ten perfections, by means of the sixth, prajñā, the wisdom that enters emptiness severs delusions completely and equals the arhat; the seventh, skillful means prajñā, emerges into the provisional for transformative function—this designation is convenient. If one takes the seventh bhūmi as equaling the arhat, matching the various bhūmis against fruitions and approaches, the seventh bhūmi directly equals the fourth fruition. These are all tentative correspondences; the sūtras and treatises are not uniform, and one must deliberate further, rather than rigidly clinging [to one view], and so forth.
