When a person wishes to rest, he folds his arms. If he wishes to feel peaceful, he closes his eyes, and a peace comes. Though the eyes are two outside, inside they are one. If the ears had covers, like the lids of the eyes, a person would close them. When a person is in the crowd, in a great noise, the thought comes: "I should go away into the solitude." If anyone is sleeping, he will want to cross his legs. If he is sitting, he will want at least to put one foot over the other. When they meet, people shake hands.
