大般涅槃經義記 4.44

4.44

Below, it explains this extensively, first refuting definite existence, beginning with citation and then refutation. If milk contained cheese, their substance and taste should be identical; 'why then are their substance and taste distinct?' That milk is cold while cheese is hot is the difference in their substance; that milk is sweet while cheese is sour is the difference in their taste; their colours are also different, but this is omitted and not detailed. That substance and taste are each distinct shows that it is not inherently pre-existent. From 'therefore' downward is the conclusion.
