金光明最勝王經疏 5.289

5.289

釋名者，梵云摩訶（此云大）薩羅悉知婆底（此云辨才）提婆仳（此云天女）。初散釋大義略四，如《大莊嚴論》云「復有四大：一勝出大，於三有五趣中而勝出故。二寂靜大，隨向無住處涅槃故。三功德大，福智二聚增長故。四者利物大，常依大悲不捨眾生故。」辨才即四辨才，即捷智，才即藝能，有捷智藝能，故云辨才。即此辨才為四種大之所攝故，名為大辨。神用自在光潔名天，亦即第一義天。天有大辨才，大辨才天即女，故云大辨才天女。真諦三藏云：「此第九地菩薩具四辨才，復能施他，故立此號。」

Regarding the explanation of the name: in Sanskrit it is Mahā- (here rendered 'Great') Sarasvatī (here rendered 'Eloquence') Devi (here rendered 'Goddess'). First, roughly explaining the meaning of 'Great,' there are in brief four, as the Mahālaṃkāra-śāstra states: 'There are further four greatnesses: first, transcendent greatness, because it is transcendent above the three realms of existence and the five destinies; second, tranquil greatness, because it conforms toward non-abiding nirvāṇa; third, greatness of merit, because the two accumulations of merit and wisdom increase; fourth, greatness of benefiting beings, because it always relies on great compassion and does not abandon sentient beings.' 'Eloquence' refers to the four unobstructed eloquences, which are swift intellect, and 'talents' are arts and skills; possessing swift intellect, arts, and skills, it is called 'eloquence.' Because this very eloquence is subsumed by the four kinds of greatness, she is named 'Great Eloquence.' Spiritual efficacy, sovereignty, brightness, and purity are called 'deva' (celestial), which also refers to the heaven of the ultimate truth. The deva possesses great eloquence, and the deity of great eloquence is a goddess (devī); hence she is called 'the Goddess Mahāsarasvatī.' Tripiṭaka Master Paramārtha said: 'This bodhisattva of the ninth stage is endowed with the four unobstructed eloquences and is furthermore capable of bestowing them upon others; hence this name is established.'
