US-P18.041ab ।US-P18.041cd ॥
In plain words
This simply denies the obscuration by a shadow; it does not establish that the shadow has true existence. After all, a statement concerning one matter cannot establish an entirely different reality.
Close to the Sanskrit
This is a negation of being overcome by a shadow, but not an establishment of reality. For a sentence situated regarding one object does not speak of another object.
