Foundations of T'ien T'ai Philosophy, p 224If we utilize this [classification of] crude and subtle to list the five flavors, the milk teachings include two types of [understanding] conditioned co-arising, one part crude [the Distinct Teaching] and one part subtle [the Perfect Teaching]. The cream teachings are just crude [the Tripiṭaka Teaching]. The curds teachings are three parts crude [Tripiṭaka, Shared, and Distinct] and one part subtle. The butter teachings are two parts crude [Shared and Distinct] and one part subtle. The Lotus Sūtra [the ghee teachings] teach only the one subtle part. This is called clarifying the subtle [understanding of] conditioned co-arising in contrast to the crude [understanding of] conditioned co-arising.
