大般涅槃經義記 4.41

4.41

前難有中，「如佛所說乳中有酪，是義云何」牒以直問，下就設難。難有四句：一以生難有，「若言乳中定有酪相，細故不見」舉佛有義，「云何說」下以生難破，「從乳新生」明非本有；二「若本無」下立理重徵，本無今有，可名為生，如其先有，云何名生？三「若言乳中定有」已下舉因類破，草是乳因，舉彼草中先有性乳，類破乳中先有性酪。「若言乳中定有酪相」重牒前有，「草應有乳」正類破之；四「如是乳中亦應有草」舉果類破，恐佛被徵說草有乳，故今類破乳應有草，斯乃舉果反類其因。

In the preceding refutation of 'existence', the text cites to question directly: 'Regarding what the Buddha has stated, that there is cheese within milk—what is the meaning of this?' Below, objections are formulated. The objections consist of four clauses. First, refuting existence by means of origination: 'If it is asserted that the characteristic of cheese definitely exists within milk, but is not seen because it is subtle' cites the Buddha's assertion of existence, while from 'why is it said' downward, it refutes it through origination; 'newly originated from milk' shows that it does not inherently pre-exist. Second, from 'if originally non-existent' downward, it establishes reasoning to press the inquiry further: having been originally non-existent and now existing, it can be called origination; if it already pre-existed, how could it be called origination? Third, from 'if it is asserted that definitely within milk' downward, it cites the cause to refute by analogy: grass is the cause of milk; by citing that within that grass there pre-exists the nature of milk, it refutes by analogy that within milk there pre-exists the nature of cheese. 'If it is asserted that within milk there definitely exists the characteristic of cheese' recites the preceding assertion of existence, and 'grass should contain milk' properly refutes it by analogy. Fourth, 'likewise within milk there should also be grass' cites the effect to refute by analogy: fearing that the Buddha, when pressed, might claim that grass contains milk, it now refutes by analogy that milk should contain grass; this is citing the effect to analogously reverse upon its cause.
