When asked if there a burning rage deep inside after he had been held a political prisoner for more than a decade, Datuk Seri Anwar Ibrahim said even though prison was tough and dehumanising, it had taught him not to harbour anger.<br /><br />The PKR president and Port Dickson MP said that at the Law Asia Conference in Petaling Jaya on Friday, adding that instead, being in prison had allowed him to read a lot of books including the Quran, the works of Wiliam Shakespeare, Sri Aurobindo, Russian novelist Fyodor Dostoevsky and more.
