妙法蓮華經玄義 7.167

7.167

此應四句：帶麁妙，即別教也；不帶麁妙，即圓教也；帶妙麁，即通教也；不帶妙麁，即三藏也。又帶麁妙，如通；不帶麁妙，如圓；亦帶麁亦不帶麁，如別；非帶非不帶，如圓接別、如圓別接通。又約五味：麁不帶妙如酪；妙不帶麁如醍醐；亦帶麁亦不帶麁如生、熟蘇；非帶麁非不帶麁如乳（云云）。

This admits of four propositions: the wondrous that carries the coarse is the distinctive teaching; the wondrous that does not carry the coarse is the perfect teaching; the coarse that carries the wondrous is the shared teaching; the coarse that does not carry the wondrous is the tripiṭaka teaching. Furthermore, the wondrous that carries the coarse is like the shared; the wondrous that does not carry the coarse is like the perfect; that which both carries the coarse and does not carry the coarse is like the distinctive; that which neither carries nor does not carry [the coarse] is like the perfect connecting to the distinctive, or the perfect and distinctive connecting to the shared. Furthermore, in terms of the five flavors: the coarse that does not carry the wondrous is like curd; the wondrous that does not carry the coarse is like clarified butter; that which both carries the coarse and does not carry the coarse is like raw and cooked butter; that which neither carries the coarse nor does not carry the coarse is like milk (and so forth).
