Pesachim 110b - Body-language and Witchcraft

There are invisible forces in the world that are potentially negative and even destructive. Our immunity to them depends on who we are and how we act. In this episode we see how althought these ideas are difficult to relate to, in the Halachik conversation they are drawn upon for issues sometimes not directly relating to them. In this case the subtly complex relationship between a man and his ex-wife is central.
