We need material development, but we need to understand that by itself it doesn't bring peace of mind.
Dalai LamaIf 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.
