First be selfish, first transform yourself.

Your life in peace, in joy, in health, can be a great source of nourishment for people who are starving for spiritual food. People are not really starving for material things. Material richness is very simple: just a little more technology, a little more science, and people can be rich. The real problem is how to be inwardly rich. And when you are outwardly rich you will be surprised -- for the first time you become more acutely, more keenly aware of your inner poverty. For the first time all meaning in life disappears when you are outwardly rich, because in contrast, the inner poverty can be seen more clearly. Outside there is light all around and inside you are a dark island.

The rich man knows his poverty more than the poor person, because the poor person has no contrast. Outside there is darkness, inside there is darkness; he knows darkness is what life is. But when there is light outside you become desirous of a new phenomenon: you long for inner light. When you see that richness is possible outside, why can't you be rich inside?
