The complaint gives the whole enterprise away. A man who starves his body and then asks why the account has not been settled was never seeking truth; he was buying it, and the price he offered was his own suffering. The ego loves such a bargain, since austerity feeds it a new food, the pride of belonging to the few who deny themselves.
Torture changes nothing in the one doing the torturing, which is why the same man can go hungry all day and still squeeze his laborers by evening. The body is innocent, and punishing it leaves the mind exactly as it was, only more certain of its own virtue. Watching transforms, and watching gives the ego nothing to display.
