808. Their minds exhibit such similarity that they form close friendships with their compatriots, but rarely with others. They also help one another, and like sincerity. They are patriotic and jealous of their country's honour. They look on foreigners like someone from the roof of his palace turning a telescope upon those who live or wander about outside the town. Their internal politics engross their minds and fill their hearts, sometimes so much so that they withdraw their spirits from studies of more exalted range, the means by which higher intelligence is acquired. Those who devote themselves to such studies in high school learn these things in their youth, but they prove to be transient like atmospheric phenomena. None the less they serve to enliven their rational faculty and make them sparkle, so that they form beautiful pictures, as a crystal prism exposed to sunlight forms rainbows and tinges a screen placed behind it with glowing colours.
