This resonated.

If there is to be peace in the world,
there must be peace in the nations.

If there is to be peace in the nations,
there must be peace in the cities.

If there is to be peace in the cities,
there must be peace between neighbours.

If there is to be peace between neighbours,
there must be peace in the home.

If there is to be peace in the home,
there must be peace in the heart.

– Lao Tzu (570-490 BC)
