I believe that at every level of society the key to a happier world is the growth of compassion. We do not need to become religious, nor do we need to believe in an ideology. All that is necessary is for each of us to develop our good human qualities.
If I were to die today, I would have some concern for Tibet. But I know that I have personally done as much as I can to use my existence for others. So I have no regret.
The purpose of all the major religious traditions is not to construct big temples on the outside, but to create temples of goodness and compassion inside, in our hearts.

If humanity is to survive, happiness and inner balance are crucial. Otherwise the lives of our children and their children are more likely to be unhappy, desperate and short. Material development certainly contributes to happiness - to some extent - and a comfortable way of life. But this is not sufficient. To achieve a deeper level of happiness we cannot neglect our inner development.
By developing a sense of respect for others and a concern for their welfare, we reduce our own selfishness, which is the source of all problems, and enhance our sense of kindness, which is a natural source of goodness.
