遊心安樂道 1.23

1.23

此言佛智，是總標句；下之四句各顯四智。不思議智者，是成所作智，此智能作不思議事，謂如不過丈六之身，而無能見頂者；不增毛孔之量，而遍十方世界；一念稱名，永滅多劫重罪；十念念德，能生界外勝報。如是等事，非其所測，是故名為不思議智。不可稱智者，是妙觀察智，此智觀察不可稱境，謂一切法如幻、如夢，非有、非無，離言絕慮，非逐言者所能稱量，是故名為不可稱智。大乘廣智者，是平等性智，此智廣度，不同小乘，謂遊無我，故無不我；無不我，故無不等攝，以此同體智力，普載無邊有情，皆全同至無上菩提，是故名為大乘廣智。無等、無倫、最上勝智者，正是如來大圓鏡智，始轉本識，方歸心原，一切種境，無不圓照，是名為大圓鏡智。此一中智，有五殊勝，如解脫身，二乘同得如是鏡智，此一智中，正是法身，非彼所共，故名無等，是一勝也；如前三智，菩薩漸得，大圓鏡智，唯佛頓證，更無餘類，故名無倫，是二勝也；過於不思議智為最，踰於不可稱智為上，寬於大乘廣智為勝，是為第三四五勝也，是故名為無等、無倫、最上勝智，是顯四疑所迷境也。

Here, 'Buddha's wisdom' is the general heading; the four phrases below each reveal one of the four wisdoms. 'Inconceivable wisdom' is the wisdom of accomplishing actions (kṛty-anuṣṭhāna-jñāna). This wisdom can accomplish inconceivable things, such as not exceeding a sixteen-foot body yet having an invisible crown; not increasing the size of a pore yet pervading the worlds of the ten directions; in a single thought invoking the name, eternally extinguishing grave sins of many kalpas; in ten thoughts reciting the virtues, attaining rebirth in the superior reward beyond the realms. Such matters cannot be fathomed; therefore it is called inconceivable wisdom. 'Ineffable wisdom' is the marvelous observing wisdom (pratyavekṣaṇa-jñāna). This wisdom observes ineffable objects: namely, that all phenomena are like illusions, like dreams, neither existent nor nonexistent, beyond words and severed from thought, unable to be measured by those who follow words; therefore it is called ineffable wisdom. 'Vast wisdom of the Great Vehicle' is the wisdom of essential equality (samatā-jñāna). This wisdom delivers widely, unlike the Small Vehicle: namely, by roaming in selflessness, there is nothing that is not oneself; because there is nothing that is not oneself, there is nothing that is not equally gathered in. With this wisdom-power of identical essence, it universally carries boundless sentient beings, all equally reaching unexcelled bodhi; therefore it is called the vast wisdom of the Great Vehicle. 'Supreme, peerless, incomparable wisdom' is precisely the Tathāgata's great perfect mirror wisdom (ādarśa-jñāna). When the fundamental consciousness is first transformed, it returns to the source of mind, and all kinds of objects are illuminated completely without exception; this is called the great perfect mirror wisdom. This single wisdom possesses five superiorities: just as with the body of liberation, which the two vehicles equally attain, so too with this mirror wisdom—within this single wisdom, it is precisely the dharmakāya and is not shared with them; hence it is called 'peerless,' which is the first superiority. Like the previous three wisdoms, which bodhisattvas attain gradually, the great perfect mirror wisdom is realized suddenly by the Buddha alone, with no other kind comparable; hence it is called 'incomparable,' which is the second superiority. Exceeding the inconceivable wisdom, it is the 'most'; transcending the ineffable wisdom, it is the 'highest'; being broader than the vast wisdom of the Great Vehicle, it is the 'supreme'—these are the third, fourth, and fifth superiorities. Therefore it is called the supreme, peerless, incomparable wisdom. This reveals the objects about which the four doubts are confused.
