大方廣佛華嚴經疏 31.16

31.16

五標法主。論云「何故菩薩說此法門？為令增長諸菩薩力故。」謂彼同類而能爾故。菩薩眾多，何故唯金剛藏說？論答云「一切煩惱難壞，此法能破，善根堅實猶如金剛，故不異名說。」此釋金剛，謂表地智有堅利二義，如金剛故。能壞煩惱即是利義，下釋藏義。論先問云「何故名金剛藏？」此問意云：為以藏攝金剛名金剛藏？為以金剛而為藏耶？上即有財、下即持業，而論雙順二句，順後句云「藏即名堅，其猶樹藏。」謂如樹心堅密能生長枝葉華實，地智亦爾能生因果，此就能藏名藏。次順上句云「又如懷孕在藏，是故堅如金剛，如金剛藏。」此謂子孕在胎藏中，善業所持堅不可壞，而得生長。此就所藏名藏。二喻俱有生長之義。論下廣合云「是諸善根，一切餘善根中其力最上，猶如金剛，亦能生成人天道行，諸餘善根所不能壞，故名金剛藏。」此之一合通上二喻。是諸善根，謂無漏善。餘諸善根，即二乘地前。今無漏善於餘善中，如孕在於胎藏。其力最上，雙合二喻堅義；亦能生成，通合二喻生長之義。其力最上猶如金剛，當體名堅。餘不能壞，對他名堅等。

Fifth, identifying the master of the teaching. The treatise says: "Why did a bodhisattva teach this Dharma gate? To increase the power of all bodhisattvas." That is because someone of their own kind could do so. When bodhisattvas are so numerous, why did only Vajragarbha speak? The treatise answers: "All afflictions are difficult to break, but this Dharma can shatter them; his roots of goodness are firm and solid like a diamond, so it was spoken under no other name." This explains "Vajra," meaning that stage-wisdom has the two meanings of hardness and sharpness, like a diamond. Being able to destroy afflictions is the meaning of sharpness; below, the meaning of "Garbha" is explained. The treatise first asks: "Why is he called Vajragarbha?" The intent of this question is: Is he called Vajragarbha because he contains the diamond in a treasury, or because he takes the diamond as a treasury? The former is a bahuvrīhi compound, the latter a karmadhāraya compound; yet the treatise accords with both lines. According with the latter line, it says: "Garbha means firm, just like the core of a tree." That is, just as the core of a tree is firm and dense, able to generate and grow branches, leaves, flowers, and fruits, so too stage-wisdom can generate causes and fruits; this names the treasury in terms of what can contain. Next, according with the former line, it says: "Furthermore, like being pregnant in the womb, it is therefore firm like a diamond, like a diamond treasury." This means that when a fetus is inside the womb, preserved by wholesome karma, it is firm and indestructible, and able to grow. This names the treasury in terms of what is contained. Both similes have the meaning of generating and growing. The treatise below extensively combines them: "These roots of goodness have the highest power among all other roots of goodness, like a diamond, and are also able to generate practices for the paths of humans and devas, indestructible by any other roots of goodness; therefore he is named Vajragarbha." This single synthesis applies to both similes above. "These roots of goodness" refers to uncontaminated goodness. "All other roots of goodness" refers to the Two Vehicles and prior to the stages. Now uncontaminated goodness among other goods is like being pregnant in the womb. "Its power is highest" synthesizes the meaning of firmness in both similes; "also able to generate" generally synthesizes the meaning of generating and growing in both similes. Having the highest power like a diamond is called firm in its own essence; being indestructible by others is called firm in contrast to others, and so on.
