法華玄論 9.17

9.17

Answer: It is indeed as you ask. However, Prabhūtaratna made this very matter his vow, and therefore it opens the root and traces. Furthermore, the reason Prabhūtaratna's vow is clarified is that because of the stūpa's appearance, he used an ancient buddha to clarify that the dharmakāya is eternal; because of the original vow, he gathered the transformation bodies to reveal that the root is one. Expressing profound principle with concise events is indeed the skillful means of the consummate person. Moreover, it shows that Prabhūtaratna's causes, fruits, vows, and practices all benefit beings: clarifying the appearance of the stūpa refers to benefiting beings through the fruit; citing the original vow refers to aiding conditions through the cause. Furthermore, the welling forth of the stūpa and praising refers to benefiting beings through practice; matching the original vow refers to aiding conditions through vows. In addition, when Prabhūtaratna's stūpa welled forth, an ancient buddha descended upon the assembly; because of the original vow, transformation bodies gathered like clouds, and when the assembly beheld them, they gave rise to a sense of wonder, revered the Lotus Sūtra, and broadly planted roots of goodness. Having such great benefit, it therefore matched his original vow.
