維摩經略疏 1.133

1.133

「深信堅固」二句，二結內無畏法也。信有二種：一聞、二證。四教分別各有位次，今但約圓。若五品弟子一向聞信，信不思議三德之理，六根清淨，亦聞亦得似證；初住已上，亦聞分證；佛地但證。今諸菩薩既居高位，二信圓深，故云深信。言堅固者，二信不為內外之所壞也。「猶若金剛」，譬顯深信。金剛二義：一、利徹本際，內合二信，定慧利用窮實際也。二、體堅，萬物所不能壞。譬二信，煩惱生死所不能損。

The two clauses "Deep faith is firm and solid" are the second part, concluding the internal dharmas of fearlessness. Faith is of two kinds: first, [faith from] hearing; second, [faith from] realization. When differentiated according to the four teachings, each has its stages, but here we speak only in terms of the Perfect [Teaching]. If one considers the disciples of the five grades, they have purely faith from hearing, believing in the principle of the inconceivable three virtues; at [the stage of] purification of the six sense faculties, they have both hearing and an attainment resembling realization; from the first dwelling stage upward, they have both hearing and partial realization; on the buddha ground, there is only realization. Now, since these bodhisattvas already abide in high stages, their two kinds of faith are perfect and profound, and so it says "deep faith." As for "firm and solid," the two kinds of faith cannot be destroyed by the internal or the external. "Just like vajra" illustrates and reveals this deep faith. Vajra has two meanings: first, its sharpness penetrates to the original limit—internally corresponding to the two faiths, where the functions of concentration and wisdom exhaust the actual limit of reality; second, its substance is solid and cannot be broken by the myriad things—analogous to the two faiths, which cannot be damaged by afflictions or birth-and-death.
