Lesson Summary

Stains are a Rabinic decree.

Location: The location that a stain is found indicates whether it probably (or not) was discharged from the womb.

Location, general: Most commonly, stains are found opposite the private area in the undergarment, toilet seat or bed sheet.

Purity Cycle: Though stains are a Rabinic decree, the purity cycle is exactly the same as for niddah which is biblical. Specifically, five minimum days, hefsek tahara, Seven White Days, preparation, immersion.

Dismissal: However, in general, because stains are Rabinic decrees judging them is through a spirit of leniency, within halacha.
