Dalai Lama on the purpose of life, happiness, love and compassion.

Developing compassion
Some of my friends have told me that, while love and compassion are marvelous and good, they are not really very relevant. Our world, they say, is not a place where such beliefs have much influence or power. They claim that anger and hatred are so much a part of human nature that humanity will always be dominated by them. I do not agree.
 
We humans have existed in our present form for about a hundred-thousand years. I believe that if during this time the human mind had been primarily controlled by anger and hatred, our overall population would have decreased. But today, despite all our wars, we find that the human population is greater than ever. This clearly indicates to me that love and compassion predominate in the world. And this is why unpleasant events are news, compassionate activities are so much part of daily life that they are taken for granted and, therefore, largely ignored.
