The Philtrum

"In Jewish legend, the Angel of the Night, Lailah, places the fertilized soul of a child in the womb and, kindling a light so the soul can see the world from end to end, teaches it about the just and the wicked, those who follow the Torah and God's commandments and those who do not. When it comes time to be born, the angel lightly strokes the child's upper lip, leaving a small indentation. Immediately, the newborn forgets all it has seen and learned and comes into the world crying."
