「問宗用俱明智斷」等者，正由向文或以宗難用、或以用難宗，恐法雜亂，故須此問。宗是自行，用是化他，各有智斷，為同異耶？此文正問宗用智斷，然下答中於自於他各有智斷，宗是自行，用是化他故也。故以宗用釋於自他智斷不同，得名各別。前文既以自行為宗，化他為用，今此自他各有智斷，乃成自他各有宗用。宗雖有用，用屬於斷，此乃名為宗家之用。「自他智斷俱為宗」者，自行以智德為宗，化他以斷德為宗。「化他智斷俱為用」者，以自望他智斷俱為智，以他望自智斷俱為斷，文從以他望自而說，是故單云「化他智斷俱為用」也。

Regarding "Question: The central theme and function both illuminate wisdom and severance..." and so on: precisely because the preceding text either challenged function with the central theme, or challenged the central theme with function, fearing that the dharmas might be confused, this question was necessary. The central theme is one's own practice, and function is converting others; each has wisdom and severance; are they identical or different? This text directly asks about wisdom and severance in the central theme and function, yet in the answer below, each has wisdom and severance for oneself and for others, because the central theme is one's own practice and function is converting others. Therefore, using the central theme and function to explain the differences in wisdom and severance for oneself and others, their names are each distinct. Since the preceding text took one's own practice as the central theme and converting others as function, now, with oneself and others each having wisdom and severance, it turns out that oneself and others each have a central theme and function. Although the central theme has a function, the function belongs to severance; this is called the function of the central theme. "Wisdom and severance of both oneself and others are both the central theme" means that one's own practice takes the virtue of wisdom as its central theme, and converting others takes the virtue of severance as its central theme. "Wisdom and severance of converting others are both function" means that viewing others from the perspective of oneself, both wisdom and severance are wisdom, and viewing oneself from the perspective of others, both wisdom and severance are severance; the text speaks from the perspective of viewing oneself from the perspective of others, and therefore simply says, "Wisdom and severance of converting others are both function."
