In plain words
Oh mind, you are essentially non-existent. When subjected to inquiry, your reality dissolves under logic. The real never perishes and the unreal has no true birth. Yet both birth and destruction belong to you; therefore, you have no real existence.
Close to the Sanskrit
You are of the nature of non-existence here, oh mind; when examined, there is indeed no existence by logic. The real is indestructible and the unreal is without birth; but both birth and destruction belong to you. Hence real existence is not conceded to you.
