法華義疏 10.90

10.90

顯佛乘究竟為果，即顯二乘非究竟故屬於因；二乘既其是因，人天亦遠屬因攝。故五乘言之，上辨佛乘為果，攝餘四乘皆悉是因，以此詳文理應然也。

Revealing the Buddha vehicle as ultimate is the fruit; this reveals that the two vehicles, being non-ultimate, belong to the cause. Since the two vehicles are cause, humans and devas are also distantly subsumed under cause. Therefore, speaking in terms of the five vehicles, the above discerned the Buddha vehicle as the fruit, and subsumed all the remaining four vehicles under the cause. Examining the text in this way, the principle ought to be so.
