One 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.
The great benefit of science is that it can contribute tremendously to the alleviation of suffering at the physical level, but it is only through the cultivation of the qualities of the human heart and the transformation of our attitudes that we can begin to address and overcome our mental suffering...
Compassion suits our physical condition, whereas anger, fear and distrust are harmful to our well-being. Therefore, just as we learn the importance of physical hygiene to physical health, to ensure healthy minds, we need to learn some kind of emotional hygiene.
The Buddha taught some people the teachings of duality that help them avoid sin and acquire spiritual merit. To others he taught non-duality, that some find profoundly frightening.
In what is seen, there should be just the seen; In what is heard, there should be just the heard; In what is sensed, there should be just the sensed; In what is thought, there should be just the thought. He should not kill a living being, nor cause it to be killed, nor should he incite another to kill. Do not injure any being, either strong or weak in the world.
Misunderstanding may arise by confusing the Buddhist and scientific definitions of death. Within the scientific system you spoke quite validly of the death of the brain and the death of heart. Different parts of the body can die separately. However, in the Buddhist system, the word death is not used in that way. You'd never speak of the death of a particular part of the body, but rather of the death of an entire person. When people say that a certain person died, we don't ask, "Well, which part died?"
It may seem unrealistic to think we can ever become free from hatred, but Buddhists have systematic methods for gradually developing a tolerance powerful enough to give such freedom.
When one drives away the negligent through vigilance, he climbs the heights of wisdom, and can see the suffering masses. Serene, you look upon the lost like one that stands on a mountain sees those that stand upon the plain.
