When a person is angry with another person, that person is removed from their heart. That's why the physical reaction is to shout. The greater the distance, the louder the shouting. But when individuals are in love, they speak softly, and when they are further in love, no words are needed.
Do not be daunted by the enormity of the world's grief. Do justly, now. Love mercy, now. Walk humbly, now. You are not obligated to complete the work, but neither are you free to abandon it.
