三彌勒經疏 1.81

1.81

經曰「既發願已」以下，第二所願果遂。此中五：一作宮、二作園、三作坐、四作柱、五天宮天女寶色皆同。是初也。瑠璃者，碧色也。頗梨者，紅色也。額上珠舉碧紅二色為首，餘眾色類一切皆具足也。紺者，《說文》言帛染青，今此云紫紺。摩尼者，青而含赤色珠也。四十九重者，為表彌勒超度四十心及初地等前九地，今迹在第十故。九億天子者，為表能超因品九品故。然方便時由信等五根成熟故，云五億天女也。四弘誓願者，《七佛經》曰「一覆度一切眾生如橋船也。二普含萬物如大虛。三願我身如藥樹，聞者患苦皆除也。四願我成佛時所度眾生如恒沙也。」《菩提資糧論》云「一末度令度、二未解脫令解脫、三未蘇息令蘇息、四末寂令寂。」此二經論雖異，一義中名別耳，故不違也。發無上道心者，發大乘心。有七因緣，如《法印經》云「發菩提心有七種因：一諸佛教化、二見法欲滅、三眾生中起大悲、四菩薩教化、五因布施故、六為覺他故、七聞佛三十二相八十種好故。」此七中，初三發心真菩薩，能護正法，疾成無上覺；餘四發心非真菩薩，不能護持諸佛正法，然欲疾成無上覺也。今云發心者，既因彌勒菩薩教化故，非真實也。

Where the sūtra states, "Having made these vows," onward: second, this explains the fulfillment of the vows. Within this there are five parts: first, making the palaces; second, making the parks; third, making the seats; fourth, making the pillars; and fifth, the celestial palaces and devīs sharing the same gemlike colors. This is the first.
"Vaidūrya" means an azure-blue color. "Sphatika" means a red color. By setting the pearls on their foreheads with azure-blue and red as the foremost, all the other various colors are fully provided. "Deep blue-black" (gàn): the Shuowen says it is silk dyed blue; here it refers to purple-black. "Mani" is a blue pearl that contains a red hue. The "forty-nine tiers" signify Maitreya's surpassing of the forty minds and the previous nine grounds beginning with the first ground, with his present trace residing on the tenth [ground]. The "nine hundred million devaputras" signify the ability to transcend the nine grades of causal stages. However, at the time of skillful means, due to the maturation of the five faculties such as faith, it speaks of "five hundred million devīs."
Regarding the "four great vows," the Seven Buddhas Sūtra states: "First, to ferry over all sentient beings universally, like a bridge and a boat. Second, to encompass the myriad things universally, like the great void. Third, I vow that my body be like a medicinal tree, so that those who hear of it have all their afflictions and sufferings removed. Fourth, I vow that when I attain buddhahood, the sentient beings delivered will be like the sands of the Ganges." The Bodhisaṃbhāraśāstra states: "First, to cause those who have not crossed over to cross over; second, to cause those who are not liberated to be liberated; third, to cause those who have not gained relief to gain relief; fourth, to cause those who are not tranquil to become tranquil." Although these two texts differ, they are distinct names within a single meaning, so they do not contradict one another.
"Producing the aspiration for the unsurpassed path" means producing the Mahāyāna mind. There are seven causes and conditions, as the Dharmamudrā Sūtra states: "Generating bodhicitta has seven causes: first, teaching by the Buddhas; second, seeing the Dharma about to disappear; third, giving rise to great compassion among sentient beings; fourth, teaching by bodhisattvas; fifth, on account of giving; sixth, for the sake of awakening others; and seventh, hearing of the Buddha's thirty-two marks and eighty minor signs." Among these seven, those who generate bodhicitta under the first three are true bodhisattvas, capable of protecting the true Dharma and swiftly realizing unsurpassed awakening; those who generate it under the remaining four are not true bodhisattvas, unable to protect and uphold the true Dharma of the Buddhas, yet still desiring swiftly to realize unsurpassed awakening. Here, the mention of generating the mind is due to the teaching of the Bodhisattva Maitreya, so it is not the authentic kind.
