Mao Tse Tung was an autocratic leader of China whose army invaded the nation of Tibet in 1950. The leader of Tibet (and all-around fabulous guy), His Holiness the Dalai Lama, was forced to flee and hasn’t been able to return to his country since. Amazingly, The Dalai Lama has credited Mao with being his greatest teacher. Mao helped him practice one of his main tenets - freeing oneself from hatefulness.
