大方廣圓覺修多羅了義經略疏 1.624

1.624

如有一段乾木，以一木燧鑽之火出，還將却燒二木。木火既盡，煙自然滅。既成灰燼，任運飛散，不同二木形質為礙。如次四節以配於法，木段喻所修幻妄，木燧喻能修幻智，煙喻離，灰喻遣。經文先云灰飛，譯之倒也，定合是煙先滅，餘灰飛散。喻中闕於顯覺，蓋文略爾，前法後合悉皆具有。若欲具之，應以地唯圓覺，由前木等本從地出，燒滅總盡，唯有地存。如種種幻化生於圓覺妙心，幻化數重遣盡，圓覺元來不動。

Just as with a piece of dry wood, drilling it with a wooden drill brings forth fire, which in turn burns both pieces of wood. When the wood and fire are consumed, the smoke naturally vanishes. Having become ashes, they scatter spontaneously, unlike the physical obstruction of the two pieces of wood. Aligning these with the dharmas according to the four stages: the piece of wood illustrates the cultivated illusory delusion; the wooden drill illustrates the illusory wisdom capable of cultivation; the smoke illustrates departure; and the ashes illustrate discarding. The sūtra text first says "the ashes fly," which is an inversion in translation; it certainly must be that smoke vanishes first, and the remaining ashes scatter. The analogy lacks the revelation of enlightenment, presumably because the text is abbreviated; the preceding dharma and subsequent application both possess it. If one wishes to complete it, one should take the ground as solely perfect enlightenment: since the wood and the rest originally came from the ground, when they are completely burned away, only the ground remains. Just as various illusions arise in the wondrous mind of perfect enlightenment, when the several tiers of illusions are completely discarded, perfect enlightenment originally remains unmoved.
