妙法蓮華經玄義 10.121

10.121

當圓教但一味，《大經》云：「雪山有草，名曰忍辱，牛若食者，即得醍醐。」正直純一，故不論五味。若無差別中作差別者，約名字即，乃至究竟即，判五味相生也。從佛出十二部即是出乳，新醫用乳也，可約四善根，就發中為五味也。

In the perfect teaching there is only one flavor. The Great Sūtra says: 'In the Snowy Mountains there is a grass named forbearance; if cattle eat it, they immediately produce clarified butter.' Being upright and pure, it therefore does not speak of five flavors. If within non-differentiation one makes distinctions, regarding the identity in words up to the ultimate identity, one determines the sequential arising of the five flavors. From the Buddha producing the twelve divisions, that is producing milk, which the new physician uses; it can be judged regarding the four wholesome roots, based on what arises within them, as the five flavors.
