妙法蓮華經玄贊 5.60

5.60

贊曰：下五頌半釋疑滅，中有四：一頌顯佛言巧心安，所以疑斷；二頌明三世佛同說方便，所以疑斷；一頌解佛說同，所以疑斷；一頌半知佛與魔道跡不同，所以疑斷。此初也。佛說有二：一法說，二喻說。「種種緣」者法說道理，「種種喻」者比況說也。外現此二巧言說法，內心安固如海不動，所以疑斷。言詞不巧，理、喻乖宗，心有動搖智迷真境，內、外可阻疑便難滅；今則不然，所以疑斷。

The Commentary says: The five and a half verses below explain the extinguishing of doubts, within which there are four parts: one verse reveals the skillfulness of the Buddha's words and the stability of his mind, by which doubt is severed; two verses clarify that the buddhas of the three times identically teach expedient means, by which doubt is severed; one verse resolves that the buddhas' teachings are identical, by which doubt is severed; one and a half verses know that the traces of the path of the Buddha and Māra are different, by which doubt is severed. This is the first. The Buddha's preaching has two aspects: first, doctrinal preaching; second, analogical preaching. "Various conditions" refers to the principles of doctrinal preaching; "various parables" refers to analogical preaching. Externally manifesting these two skillful speeches to preach the Dharma, while internally his mind is stable and unshakeable like the ocean, doubt is therefore severed. If the phrasing were unskillful, the principles and parables contradicted the tenet, and the mind wavered while wisdom was bewildered regarding the true realm, inner and outer would meet hindrance, and doubts would then be difficult to extinguish. Now, it is not so; therefore doubts are severed.
