法華論疏 2.59

2.59

言所說因果相應知者，近而為言〈方便〉一品明因果義，如云「受持讀誦甚深」等明因義，「諸佛智慧甚深無量」等明果義。遠而為言，此經唯顯一理、說一乘、唯教一人，故以一乘因果為宗。

As for the statement that 'the cause and fruit explained should be understood to be corresponding': speaking proximately, the single "Skillful Means" Chapter clarifies the meaning of cause and fruit—such passages as 'receiving, upholding, reading, and reciting the profound' clarify the meaning of cause, while 'the wisdom of the Buddhas is profoundly deep and immeasurable' and so forth clarify the meaning of fruit. Speaking comprehensively, this sūtra reveals only one principle, explains only the one vehicle, and teaches only the one person; therefore, it takes the cause and fruit of the one vehicle as its central theme.
