大方廣圓覺修多羅了義經略疏 2.1229

2.1229

此云眾園，園是眾居處故。圓覺則萬德所依，以八識海澄，流注寂滅，體遍法界，故得名大。於四智中則圓鏡也。

Here [in Chinese] rendered as 'garden of the assembly', because a garden is a place where an assembly resides. Perfect enlightenment is that on which myriad virtues rely; because the sea of the eight consciousnesses is clear, the streaming flow is quiescent, and its substance pervades the dharmadhātu, it is thus named 'great'. Among the four wisdoms, it is the great round mirror [wisdom].
