2.38

「亦有一切智」下，恐闕「道種智」三字。「總別之異名」者，觀中道是總，照二邊是別。即別而總，邊即中故，二智即一切種智；即總而別，中即邊故，一切種智即是二智。三智圓融，總別一體。

Below "also has sarvajñatā," it is feared that the three characters for "mārgākārajñatā" (道種智) are missing. "Different names for the general and the specific": contemplating the middle way is general; illuminating the two extremes is specific. Specific yet general, because the extremes are precisely the middle, the two wisdoms are precisely sarvākārajñatā; general yet specific, because the middle is precisely the extremes, sarvākārajñatā is precisely the two wisdoms. The three wisdoms are perfectly fused; general and specific are a single substance.
