When Xarnak meditates, he enters a trance-like state in which he can't be harmed in anyway. He can sometimes see through time and space, or even let enities inside his body (not possesing him, rather like a meeting place), and once left his body entirely, temporarily acesending into a being who had full control of all reality. It is not known what occured during that time, but afterwards, Xarnak returned to his mortal body, exhausted. He is unwilling to tell anyone what really happened.
