When Mother Theresa was alive, she told the rich, "Give until it hurts." If it doesn't hurt, it is just another donation to charity. But if it hurts, the pain is that of being moved and that of feeling what the poor and the weak feel.
德蕾莎修女在世時，常奉勸富有的人說：「要奉獻到心痛為止」，不痛不癢的奉獻只不過是施捨而已，而這「心痛」，其實也就是感動，對貧弱者的處境感同身受。
