大毘盧遮那成佛經疏 10.218

10.218

「行者前方便」者，如是觀行之時，若以一花獻佛，至心迴向，願令此通達一一句中解也。並下文花遍十方一切剎土普作佛事，爾時應念即成。乃至香食等事，一一如是廣說。設天大旱，或有種種災患，爾時行人一花供養，願令此旱得除、降注大雨，或願諸患自息，無不應時成就。復以此一一功德迴向菩提，普施一切眾生，如此菩提大願亦當成就，何況餘事也。前云一月者，即是心與一境相應也。一一句通達者，謂前觀字輪、觀聲輪及本尊種子，一一明了現前無有錯謬，名通達一一句也。先觀佛得成，即見圓明，隨一得成餘即成就。謂觀本尊明了之時，圓明字輪等相自然成就。此月即是月喻三昧，法性清涼乃能普現眾生心水之中，非如世間月也，但借心為喻耳。但隨一成，餘者自成，然所以具說者，至下文各有用處，故須具明觀月法用也。

Regarding 'The practitioner's preliminary upāya': When engaging in such contemplation and practice, if one offers a single flower to the Buddha and dedicates it with utmost sincerity, one should vow that this will penetrate the understanding of each and every phrase. Together with the subsequent passage where flowers pervade all realms of the ten directions to perform buddha-work everywhere, it is accomplished immediately upon thought at that time. It is expounded extensively in this way for incense, food, and so forth, each in like manner. Even if there is a great drought in the world or various calamities arise, when the practitioner offers a single flower and vows that this drought be eliminated and great rain poured down, or vows that all calamities naturally cease, there is none that is not accomplished in response to the moment. Furthermore, dedicating each of these merits toward bodhi and universally bestowing them on all sentient beings, such a great vow for bodhi will also certainly be accomplished, how much more so other matters! The 'one month' mentioned previously refers to the mind corresponding with a single object. 'Comprehending phrase by phrase' means that in the previous contemplation of the syllable wheel, sound wheel, and seed-syllables of the personal deity, each is clearly manifest before one without error; this is called comprehending phrase by phrase. First contemplating the Buddha to success, one then sees the round brilliance; when any one is accomplished, the rest are accomplished. This means that when the personal deity is clearly visualized, the round brightness, the syllable wheel, and other marks are naturally accomplished. This moon is the moon-analogy samādhi; the nature of phenomena (dharmatā) is pure and cool, and can therefore universally manifest in the mind-water of sentient beings—it is not like the worldly moon, but merely uses the mind as an analogy. When any one is accomplished, the others are naturally accomplished. However, the reason it is expounded in full is that in the text below each has its specific application, so the method and function of contemplating the moon must be explained in full.
