@TheDestroyer Adi Shankaracharya addresses this issue in a way that I find totally unsatisfactory: "And should you ask who then is characterised by the absence of true knowledge, we reply: You yourself who ask this question!--And if you retort, 'But I am the Lord as declared by scripture,' we reply, 'Very well, if you have arrived at that knowledge, then there is nobody who does not possess such knowledge.'"
