Overcoming negative tendencies and enhancing positive potential are the very essence of the spiritual path.
Dalai LamaOne Mongolian leader became a very, very brutal dictator and eventually became a murderer. Previously, he was a monk, and then he became a revolutionary. Under the influence of his new ideology, he actually killed his own teacher. Pol Pot's family background was Buddhist. Whether he himself was a Buddhist at a young age, I don't know. Even Chairman Mao's family background was Buddhist. So one day, if the Dalai Lama becomes a mass murderer, he will become the most deadly of mass murderers.
Dalai LamaThe real test of compassion is not what we say in abstract discussions but how we conduct ourselves in daily life.
