Immersion for a Woman Whose Husband is Not at Home

It is written in the books that it is not good for a woman to immerse when her husband will not be with her that night, as it can attract negative forces. Therefore, it is preferable to wait with the immersion until the day he returns. However, if there is a chance that he will be released earlier, or there is another reason to immerse before he returns, it is permissible to immerse and place a knife in the bed or sleep with a child in the bed, which protects from these forces.
