A beautiful teaching from the Babylonian Talmud:

According to this medieval Jewish text, the angel Lailah lives in the womb and watches over the embryo until it is time be to be born. The angel teaches the unborn child everything there is to know about the mysteries of life and his or her own soul. Lailah also places a lighted candle at the head of the unborn infant, so he or she can see from one end of the world to the other. When the time comes for the child to be born, the angel Lailah puts her finger in front of her own mouth as if to say “shhhh” and then presses the upper lip of the child so all the memories are forgotten. According to this story, the light touch on the child’s lip leaves a small indentation about the lip called a philtrum, which is something we all have.

I think, perhaps, the angel Lailah just did not press quite hard enough on some children’s lips and this is why they come into this current life with soul memories. How blessed we are to have these children share their wisdom with us. How important it is to listen, listen very carefully.
