大般涅槃經義記 4.44

4.44

下廣顯之，先破定有，初牒、次破。若乳有酪，體味應同，「云何而得體味各異」？乳冷酪熱是其體異，乳甜酪酢是其味異，其色亦異略而不辨。體味各異明非本有。「是故」下結。

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.
