A house without walls when all houses have no walls
In Kiribati I lived in a house without walls and it was such a moving act to lie down on a mat next to the others with the full moon as our blanket.
For those who live in cold countries, this exercise might be difficult but, by closing our eyes, we can imagine life in a house without walls, then life in a country where all the houses have no walls, then we can expand our minds and imagine life everywhere on the planet where all houses would have no walls. Then, we will know exactly what rules it takes to live together in a world of peace. Despite our taste for freedom, there is no life or peace possible in our hearts and on the Earth without some life rules in place.
