The word passion comes from Latin root pati-, meaning suffering, or enduring. Thus, compassion means to suffer-with: the compassionate aren’t immune to other people’s pain. And passion is, at its core, a form of pain that demands it be quenched. It’s not for the faint of heart or those who lack patience — which is not the ability to wait, but the ability to suffer.
