Rigorous poverty is our safeguard. We do not want, as has been the case with other religious orders throughout history, to begin serving the poor and then gradually move towards serving the rich. In order for us to understand and to be able to help those who lack everything, we have to live as they live. The difference lies only in the fact that those we aid are poor by force, whereas we are poor by choice.
--Mother Teresa of Calcutta, No Greater Love.
