If there is light in the soul
There will be beauty in the person.
If there is beauty in the person
There will be harmony in the house.
If there is harmony in the house
There will be order in the nation.
If there is order in the nation
There will be peace in the world.
– Chinese Proverb

Have been trying to come with a better first line, but have failed so far. Every line feels like a logical progression, except for the first one, which is rather nebulous. Like a tower build on a soft foundation. Light? in Soul? Could be the translation from Chinese to English that’s at fault.

Hm, let’s try starting with:
If there’s a smile on your face…

It’s interesting that we know what is meant by If there is light in the soul… – it’s probably the reason that there is a smile on your face… but just try to explain to a kid or an ET what that light in the soul is – and why you haven’t switched it ON.
