3.121

大品般若四十卷。案藏經目錄云。摩訶般若三十卷。光讚般若十卷。龍樹用此本。作智度論百卷。智者依此論。作疏二十卷（今在高麗未至）若放光金剛等十經。皆是晉宋間譯。至唐奘法師。始譯出大般若經六百卷。當知前十經。皆重譯之文。智者諸部文所引。正大品中義。是晉羅什譯。在唐譯大般若之前也。

The Larger Prajñāpāramitā consists of forty fascicles. According to the Canon Catalogue, the Mahāprajñā consists of thirty fascicles, and the Guangzan bore (Pañcaviṃśatisāhasrikā) consists of ten fascicles. Nāgārjuna used this text to compose the Mahāprajñāpāramitopadeśa (Zhidu lun) in one hundred fascicles. Zhiyi relied on this treatise to compose a commentary in twenty fascicles (now in Goryeo and has not yet arrived here). Sūtras such as the Fangguang [bore] and the Diamond Sūtra, ten sūtras in total, were all translated between the Jin and Song dynasties. It was not until Master Xuanzang of the Tang that the Mahāprajñāpāramitā Sūtra was first translated in its entirety in six hundred fascicles. One should know that the former ten sūtras were all separate translations of portions thereof. What Zhiyi cited in his various works were precisely the doctrines in the Larger Prajñāpāramitā, translated by Kumārajīva of the Jin, which predated the Mahāprajñā translated in the Tang.
