So I am on a few Jewish message boards and am currently following a thread about mikvah. One woman posted that she goes to mikvah sometimes when her travelling husband is out of town. A discussion ensued that had one poster telling her it was assur (forbidden) to go to the mikvah when her husband was out of town, and another saying it wasn’t assur just not advisable. Yet a third said that if she goes, she needs to either sleep with a knife under her pillow, or wearing some of her husband’s clothes – eg socks. I am guessing that this is of kabbalistic origin.
Do any of my JewCrew have any insight onto this custom? I have never heard of it before!
