When our attitude towards our material possessions and wealth is not proper, it can lead to an extreme attachment towards such things as our property, houses and belongings. This can lead to an inability to feel contented. If that happens, then one will always remain in a state of dissatisfaction, always wanting more. In a way, one is then really poor, because the suffering of poverty is the suffering of wanting something and feeling the lack of it.
— Dalai Lama
