妙法蓮華經玄義 3.130

3.130

Regarding coarse and wondrous: although the Buddhas of the Tripiṭaka and Shared [teachings] have the name 'wisdom of all modes', there is no separate principle, and they do not destroy separate delusions; since this wisdom is not accomplished [there], it is not employed. As for the wisdom of the middle merging into emptiness: although the cause of the middle way is spoken of, the two wisdoms are accomplished through the Shared portal, and subsequent illumination of the middle way has no vast function. Because it relies on an unskillful teaching and the effect is not interfused, it is coarse. Next, as for the tathāgatagarbha merging into the wisdom of emptiness: although the principle of the effect of the teaching is interfused, because the cause is the Shared portal, it is also called coarse. As for the middle in contrast with the two wisdoms: although it does not rely on the Shared, the three wisdoms are distinct and separate, and the effect of the teaching is not yet interfused; therefore it is coarse. As for the tathāgatagarbha merging into the middle: although interfused in the effect, because the cause is the Distinct portal, this cause is also coarse. As for the round three wisdoms: the cause is round and the effect is round; the cause is wondrous and the effect is wondrous; the truth is wondrous and the wisdom is wondrous; 'directly setting aside expedients, one only expounds the unsurpassed path'; therefore it is wondrous wisdom.
