। ॥ २२ ॥
In plain words
If everyday experience confirms that when every perceivable object is sublated, nothing whatsoever remains—what is thus taken as 'nothing whatsoever' is established by the Vedas to be Brahman itself.
Close to the Sanskrit
If it is established by common experience that upon the sublation of all perceived objects nothing at all remains, that which is established as 'nothing at all' is indeed Brahman, as established by the Vedas.
