Buddhist philosophy tells us that all personal unhappiness and interpersonal conflict lie in the “three poisons”: craving, anger, and delusion. It also provides antidotes of astonishing psychological sophistication--which are now being confirmed by modern neuroscience. With new high-tech devices, scientists can peer inside the brain centers that calm the inner storms of rage and fear. They also can demonstrate that awareness-training strategies such as meditation strengthen emotional stability—and greatly enhance our positive moods.
