妙法蓮華經玄義 10.119

10.119

當通教中五味者：《大經》三十二云：「凡夫佛性如雜血乳，血者，即是無明、行等一切煩惱；乳者，即善五陰。是故我說，從諸煩惱及善五陰得三菩提，如眾生身皆從精血而得成就，佛性亦爾。須陀洹、斯陀含斷少煩惱如真乳，阿那含如酪，阿羅漢如生蘇，支佛至十地菩薩如熟蘇，佛如醍醐。」超果不定（云云）。

Regarding the five flavors within the shared teaching: Chapter 32 of the Great Sūtra says: 'The buddha-nature of ordinary beings is like milk mixed with blood. Blood refers to all afflictions such as ignorance and formative karmic action; milk refers to the wholesome five aggregates. Therefore I say: from all afflictions and the wholesome five aggregates one attains sambodhi, just as the bodies of sentient beings are all accomplished from semen and blood; buddha-nature is also like this. Srotaāpannas and sakṛdāgamins who have severed a few afflictions are like pure milk; anāgamins are like curd; arhats are like raw butter; pratyekabuddhas up to bodhisattvas of the tenth bhūmi are like ripened butter; Buddhas are like clarified butter.' Transcending fruits is unfixed (and so forth).
