If you realize that primitive societies couldn’t tell the difference between a rabbit and a hare, then you’ll understand this ancient logic as to why the rabbit’s foot is a symbol of good luck.
Hares are born with their eyes open, giving them knowledge of prenatal life.
The rabbit burrows underground and shares secrets with the underworld.
Finally, both animals’ incredible fertility could be shared by carrying the rabbit’s foot as a phallus of good luck.
