Second, determining the crude and the subtle: the discourses on truth in the Great and Lesser Vehicles do not go beyond these four. When the teaching, practice, and realization are not integrated, they are crude; when the teaching is integrated but practice and realization are not yet integrated, they are also crude; when all are integrated, they are subtle. If classified according to the five flavors: the teaching of the milk [period] has two kinds, neither of which is heard by the two vehicles; because the great is segregated from the small, one is crude and one is subtle. The teaching of the curd [period] has one kind, not used by the Mahāyāna; because the small is segregated from the great, faculties are ruined, deaf and dumb, therefore it is crude. The teaching of the raw butter [period] has four kinds: one refutes the three, two do not enter the two. Although one enters, one teaching is not integrated; therefore three are crude and one is subtle. The teaching of the cooked butter [period] has three kinds: one refutes two, one enters one, and one does not enter one. Although one enters one, the teaching is not integrated; therefore two are crude and one is subtle. The teaching of the ghee [period] has only one kind of four truths: purely subtle without the crude. This is clarifying the subtle by contrast with the crude (and so on).
