3.237

至能下，承前以明。玄根喻真，拔喻於證。未始，二意：一未猶無也，理無始故，智始會時非照今有。二智雖極真未始照故，如前云虛心等。群動，俗也。權應之時，初無應相，故云靜心。後二句，如次成上二智無相。自然者，感而後應，不加功力。《起信》云：「自然而有不思議業，能現十方利益眾生。」

From "he can ultimately" downward, it continues from what precedes to clarify. "Profound root" is a metaphor for the true; "uproot" is a metaphor for realization. "Before the beginning" has two meanings: first, "before" means non-being; because principle is without beginning, when wisdom first accords with it, it does not illuminate a newly present existence. Second, although wisdom reaches the ultimate truth, it has never yet had the mark of illuminating; as said before, "empty mind," etc. "Manifold movements" refers to the mundane. At the time of provisional response, originally there is no mark of responding, hence it is said "quiet the mind." The latter two clauses sequentially complete the marklessness of the two wisdoms above. "Spontaneity": responding after being stimulated, without exerting effort. The Awakening of Faith says: "Spontaneously possessing inconceivable karma, able to appear throughout the ten directions to benefit sentient beings."
