法華玄義釋籤 2.49

2.49

次文證宗中二：先引，次「即是」下釋。初文亦是文殊釋伏疑文也。次釋中先約迹、次約本。迹門約弟子因，本門約佛果也。師非無因、弟子有果，且互舉耳。

Next, the text verifying the principal theme has two: first, citing; next, from "That is" onward, explaining. The first text is also Mañjuśrī's text resolving the concealed doubt. Next, in the explanation, it first takes the trace and next takes the origin. The trace gate treats the disciple's cause, and the origin gate treats the Buddha's fruit. The master is not without cause, and the disciples have fruit; they are merely mentioned interchangeably.
