法華義疏 7.181

7.181

「復逕少時」下，第九、陶練小心譬。所以須此譬者，二乘聞《大品》既不悟，何因緣故至《法華》便解耶？故須明《大品》已後諸方等經陶練其心，令稍鄙小心漸欣大道，至於《法華》方得取悟也。

From "After a short time had passed again" onwards is the ninth [section], the parable of smelting and refining the small mind. Why is this parable necessary? Since the two vehicles did not awaken upon hearing the Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra, by what causes and conditions did they understand upon reaching the Lotus Sūtra? Therefore, it is necessary to explain that the various Vaipulya sūtras subsequent to the Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra smelted and refined their minds, causing them gradually to disdain their small minds and progressively aspire to the great path, so that only upon reaching the Lotus Sūtra could they attain awakening.
