1.2 (tr. Abraham Cohen):
The seven worlds which a man experiences: At one year old he is like a king, placed in a covered litter, and all embrace and kiss him. At two or three he is like a pig which pokes about the sewers. At ten he jumps about like a kid. At twenty he is like a neighing horse; he adorns his person and seeks a wife. Having married, he is like an ass, bearing a heavy burden. Then having become the father of children, he grows bold like a dog to procure sustenance for them. When finally he has grown old, he is bent like a monkey.
