大毘盧遮那成佛經疏 3.43

3.43

次偈「過去等正覺，及與未來世，現在諸世尊，住饒益眾生。如是諸賢者，解真言妙法，勤勇獲種智，坐無相菩提」者，即是開十方三世諸佛一切方便門，唯以一道成佛，更無餘道也，以佛佛同道故。今還引諸佛證明，是事如《法花》中廣說。又言住饒益者，謂多所饒益安樂眾生，即是如來住處也。諸賢者，即是如來。由普賢願行悉以圓極，故以為稱。皆由解此真言妙法得大勤勇、成一切智，就偈頌省文，故云種智也。坐於諸法寂滅，即是菩提，非已成、今成、當成，無法可觀、不從他得，當有何相耶？此菩提，不可說以示人，故次偈更以外迹明之。

The next verse: / "Past fully enlightened ones, / And those of future times, / And all present World-Honoured Ones, / Abide in benefiting sentient beings. / All such virtuous ones, / Understanding the wondrous Dharma of mantras, / With diligence obtain all-knowledge, / And sit in signless bodhi": / this opens up all the upāya gateways of the buddhas of the ten directions and the three times, that they achieve buddhahood solely through a single path and there is no other path, because buddhas share the same path. Here he again cites all buddhas as witness, a matter extensively explained in the Lotus Sūtra. Furthermore, "abide in benefiting" means greatly benefiting and bringing peace and happiness to sentient beings, which is the abiding place of the Tathāgata. "All such virtuous ones" are the Tathāgatas. Because their vows and practices like Samantabhadra's are all fully perfected, they are called by this title. All, from understanding this wondrous Dharma of mantras, attain great diligence and accomplish sarvajñā; in accordance with the verse's abbreviation, it says "all-knowledge". Sitting in the extinction of all phenomena is bodhi; it is not already accomplished, currently accomplished, or to be accomplished; there is no dharma to be contemplated, and it is not obtained from another; what sign could it have? This bodhi cannot be spoken of to show to others, so the next verse further illustrates it through external traces.
