Words on Peace from Mother Teresa

I'm reading "No Greater Love" by Mother Teresa for a writing project I'm working on. I came across this passage today which seems especially relevant:

"Peace and war start within one's own home. If we really want peace for the world, let us start by loving one another within our families. Sometimes it is hard for us to smile at one another. . .

In order for love to be genuine, it has to be above all a love for our neighbor. We must love those who are nearest to us, in our own family. From there, love spreads toward whoever may need us."
