Windmills put the wind to work. Similarly, through meditation, you can set up an anger windmill, which will put your anger to work, drawing the living waters of compassion and creativity from the depths of your heart to help those around you. Gandhi learned this secret in South Africa. "I have learnt through bitter experience," he wrote, "the one supreme lesson to conserve my anger, and as heat conserved is transmuted into energy, even so our anger controlled can be transmuted into a power which can move the world." . . .

Harnessing his anger about the indignities that were heaped upon him and others in South Africa, he changed the world.
