This basically means that we need to check that no one gets to blown up in their head about being good about something. Even if you are good at something and you believe that you are good at it, Swedes would cut you down for thinking so. Swedenborg talks of how Sweden corresponds to the kidneys of the Grand Man. This is because of the fact that Swedes are so critical and similar to the kidneys Swedes purify their environment from any filth or incompleteness they might find. You might believe that I am exaggerating about this, but if you have ever been to Sweden you know how incredibly clean it is.
Swedes just love to tidy things up.
In Sweden you will also find how Swedes are very uptight and formal, and this because they don't want to show any faults to others because they know how critical everyone else is. I heard of a Ghanaian who came to visit Sweden once. He and a Ghanian friend of his, who already had been in Sweden for some time, went to use the subway in Stockholm. As they went down the escalator to the subway they were laughing and having a great time together, but when they went on the subway they were hit by the how quiet everyone was who sat there. From the way people looked he asked his friend if that day was a day of national mourning.
