It is in solitude that compassionate solidarity grows. In solitude we realize that nothing human is alien to us, that the roots of all conflict, war, injustice, cruelty, hatred, jealousy, and envy are deeply anchored in our own heart. In solitude our heart of stone can be turned into a heart of flesh, a rebellious heart into a contrite heart, and a closed heart into a heart that can open itself to all suffering people in a gesture of solidarity. — Henri Nouwen
