What do they do?
However, if you guessed from the picture and the title that Erathipa is a rock, well, then you'd be right. See, this rock apparently looks like a pregnant woman. I don't see it from this picture (or maybe I should say at least my wife doesn't look like this rock! (but I'd love her just as much if she did)) but then again, I did not take this picture and am going on somebody else's word that this is Erathipa.
Here is how it works, the souls of dead babies live in the rock. When a young woman walks by, one of the souls gets a second chance at life by leaping into the woman. They avoid older women, so if you are a young woman who does not want to get pregnant, you need to grab a stick and walk like you are old and leaning on a cane while talking loudly about how old you are (I'm not making that up).
I think this is a neat and disturbing idea at the same time. It does serve to give hope to both the childless and those who have the misfortune of a still birth, miscarriage, or infant death. Beats the German idea of vindictive storks delivering dead babies to families with mean children, at least.
