being poor is not because someone is penniless, but mainly because of the lonely misery in his inner world. they are green-eyed, because they are never satisfied with what they have, but are always jealous of people who are successful or who earn higher salaries. they never look at other people's devotions and contributions, but with their habit of jealousy they always feel poor and uncomfortable. it is more difficult to solve internal poverty. suppose we can look back at the past with the concept of wealth, how can we stay poor? we may well say that wealth lies in your heart and we should know how to treasure it.
