大毘盧遮那成佛經疏 3.45

3.45

次偈云「是故汝佛子，應以如是慧，方便作成就，當獲薩婆若」者，是勸發行人令求彼果。汝今幸自有心，何不證之？但當以此妙慧而作成就，不久自當成一切智也。上文，金剛手直問毘盧遮那：「云何得一切智智？」佛亦直答：「如實知自心，是名一切智智。」今此中教授義亦同。然直舉無相菩提，便即勸令修證，更無行位差別可以錯於其間。雖前品廣明諸相，作種種名字莊嚴，至論心處意皆如是也。

The next verse says: / "Therefore, you, son of the Buddha, / Should with such wisdom / Accomplish through upāya, / And you will attain sarvajñā": / this is to exhort the practitioner to seek that fruit. You now fortunately have a mind of your own; why not realize it? You should simply accomplish through this wondrous wisdom, and before long you will naturally attain sarvajñajñāna. Above, Vajrapāṇi directly asked Vairocana: "How does one obtain sarvajñajñāna?" The Buddha also directly replied: "Knowing one's own mind as it truly is, this is called sarvajñajñāna." The meaning taught here is the same. Thus, directly presenting signless bodhi, he immediately encourages them to practice and realize it, without any differences in stages of practice to be interposed therein. Although the preceding chapter extensively explained various characteristics and made diverse names and adornments, when it comes to the level of the mind, the meaning is entirely like this.
