I like very much the fact, that in this system a pause during menstruation is made. It had a huge effect on me, sticking to this rule. It is very beautiful to be let alone and be nothing at all. And I think it is very honest feminism, to not lie about the body's needs (of being wrapped in cotton and sheltered as possible from vulnerability). Because menstruating is painful, physically and mentally and I honestly can't even think straight. The brain works totally different as soon as the hormones drop and raise! Body/mind become sometimes occupied and vulnerable or sometimes very strong. Maybe we can do our best to keep our uteruses and breasts healthy when paying attention to such things.
