There was an anthropologist who visited with some undeveloped village somewhere, and somehow while he was living with them, the concept of depression came up.
The man he was talking to said oh yes we know about that. Sometimes someone will get broken in this particular way, they want to stay inside all the time and they can't get happy or feel emotion, they have very low energy, trouble with sleep, we know, we have that here too. It is evil spirits that get into the person, and so we worked out over time, what you need to do is get a whole bunch of the people who are close to that person, go over and haul them out of the house, and there's a whole ritual. It's like a big parade around the village, people have to touch them, throw arms around them, sing, we throw this type of powder on them, carry them around up on everyone's shoulders up in the sunlight. You have to do it for many hours. But most of the time it works; they get broken out from that type of thing they are suffering from, and if then if they try to make an effort from that point it's not hard for them to come back to a normal life and they are much happier. It is very important to do this ritual if you know someone who's in that state, and if we find it out pretty much the whole village will make a day to get them out and rescue them from it, because it is a terrible affliction and usually they cannot fix themselves from it on their own.
The anthropologist was fascinated and talked about depression in Western societies a little bit, and the villager suddenly got animated. Yes! I know this. I never saw it but, in the cities some foreigners came in and tried that way. You sit in a little room and you talk to a total stranger about all the things that make you sad. And you repeat this for a short time each week. It is absolutely terrible. We had to kick them out of the country.
