法華義疏 4.234

4.234

眾生待時待處以得悟故聖人化之耳，處無定也。今明有二因緣故住彼處：一者、《毘婆沙》云「有五處定，謂生處、出家處、成道處、說法處、滅度處」，三世諸佛常於此處說法故云處定。

Sentient beings await the right time and place to attain awakening, so the sage transforms them accordingly; the place is not inherently fixed. Now we clarify that there are two causes and conditions for abiding in that place: First, the *Vibhāṣā* says: "There are five fixed places, namely, the place of birth, the place of renunciation, the place of attaining the Way, the place of preaching the Dharma, and the place of passing into extinction." The Buddhas of the three times always preach the Dharma in this place, hence it is called a fixed place.
