US-P18.145ab ।US-P18.145cd ॥
In plain words
Your destruction reaches only as far as the particular that bounds it, and destruction itself you define as the ceasing of non-destruction. So on your account, cowness is nothing but the non-existence of the non-cow. But that is not the cow's own mark.
Close to the Sanskrit
Destruction has the own-characteristic as its limit; destruction is the cessation of non-destruction. For you, cowness is the non-existence of the non-cow; but that is not the cow's own characteristic.
