法華經義記 1.109

1.109

問者言：「只應入法華三昧，何故入無量定耶？」解釋者言：「若入法華三昧，云何得有為《法華》序耶？無量義處者，《無量義經》明萬善成佛，佛果是無量義所歸之處。又明如來將欲說法華義故，是故先入無量義定，表必說《法華》，即是相義；密報時眾，即是瑞也。」

The questioner asks: "One should only enter the Lotus Samādhi; why enter the Samādhi of Immeasurable Meanings?" The commentator answers: "If he had entered the Lotus Samādhi, how could there be a prologue to the Lotus Sūtra? As for the 'Place of Immeasurable Meanings,' the Sūtra of Immeasurable Meanings clarifies that myriad goods attain Buddhahood, and the Buddha-fruit is the place to which immeasurable meanings return. Furthermore, it clarifies that because the Tathāgata was about to expound the meaning of the Lotus, he therefore first entered the Samādhi of Immeasurable Meanings. Signifying that he must expound the Lotus Sūtra is the meaning of the sign; secretly intimating it to the assembly of that time is the portent."
