新華嚴經論 20.26

20.26

九明諸菩薩從誰發心者，皆於自心無始分別。無明為發心之始，達此無始無明為大圓鏡智故，即與十方毘盧遮那如來同善根故。若離此智，無成佛期，無見佛日。是故經云「如是菩薩皆與毘盧遮那往昔同善根故」，明達自無明，成大智體，諸佛共此智也。

Ninth, clarifying from whom the bodhisattvas arouse the thought [of awakening]: They all take the beginningless discrimination and ignorance of their own minds as the beginning of arousing the thought [of awakening]; because they realize that this beginningless ignorance is itself the great mirror-like wisdom, they share the same roots of goodness with Vairocana Tathāgata of the ten directions. Apart from this wisdom, there is no time of attaining buddhahood, no day of seeing the Buddha. Therefore, the sūtra says: "Such bodhisattvas have all shared roots of goodness with Vairocana in the past," clarifying that realizing one's own ignorance forms the essence of great wisdom, and all Buddhas share this wisdom.
