She said: "As we're busy trying to figure out which group is causing the problem, evil is winning...we have to change the perspective.
"We need to educate them. You have the power to be kind to them."
And the Dalai Lama said: "We are a social animal, so individuals' future depends entirely on the community. Once a tragic situation happens, don't avoid - but look at it more deeply and widely. Many positive, happy things are there if you look from a wider perspective. If you look real closely, it appears unbearable. But if you look widely you see other positive things there."
