金剛經纂要刊定記 1.117

1.117

疏冥資下一句。祈願利生也。冥闇，資助也。所述即此疏也。契合也。群機即一切眾生也。然資助加護有二種：一即顯加，謂現身說法有所見聞。二即冥加，但得智力無所視聽。今於二中唯求冥加也。以製疏釋經唯籍智力，但得冥助不須見聞。以此經云：「若以色見聲求是行邪道。」為順此教故不求顯然，凡所設教皆契理契機。今不言契理者，以疏是論文已契理故，又疏主於二利中利他偏甚。今唯言契機者，悲增之相也。

The single line from "Subtly aiding this commentary" downward is a prayer to benefit sentient beings. "Subtle" means dark [unseen], and "aid" means assistance. "What is set forth" is this very commentary. "Accord" means to harmonize. "Multitude of capacities" means all sentient beings. Now, aid and protection are of two kinds: first, manifest aid, which means manifesting a physical body to expound the Dharma, involving seeing and hearing; second, unseen aid, which means only obtaining the power of wisdom without seeing or hearing anything. Between the two, here he seeks only unseen aid. Because composing a commentary to explain a sūtra relies solely on the power of wisdom, if one only obtains unseen assistance, there is no need for seeing and hearing. For this sūtra says: "If one sees me by form or seeks me by sound, one is walking a heterodox path." In order to accord with this teaching, he does not seek manifest [aid]. Furthermore, wherever teachings are established, they must accord both with principle and with capacity. Here he does not mention according with principle because the commentary is a treatise that already accords with principle, and also because the commentary's author, between the two benefits, prioritized benefiting others. Here mentioning only according with capacity is a sign of an increase in compassion.
