The Torah, “Leviticus” (Metzora), 15:19-15:21, 15:24: If a woman has a discharge, her flesh discharging blood, she shall remain in her state of menstrual separation for seven days, and whoever touches her shall become unclean until evening. And whatever she lies on during her menstrual separation, shall become unclean, and whatever she sits on, shall become unclean. And anyone who touches her bedding, shall immerse his garments and immerse [himself] in water, and he shall remain unclean until evening. If a man cohabits with her, [the uncleanness of] her menstruation shall be upon him, and he shall be unclean for seven days, and any bedding he lies upon, shall become unclean.
This speaks about the division of the pure and the impure desires. Touching an impure desire is being infected by the Light. A spiritual contact takes place when I somehow recognize myself with my ego. Therefore I have to enter an ark and shut myself from the egoistic desires and constantly be in a spiritual shell.
The Torah, “Leviticus” (Metzora), 15:25: And a woman whose flow of blood flows for many days, outside of the time of her menstrual separation, or she has a discharge after her menstrual separation, then all the days she has her unclean discharge, she shall be unclean just like the days of her menstrual separation.
In the past women kept away from the house chores during their monthly period and waited until it was over. Today there are tribes who still keep this custom.
When the period was over a woman used to purify herself and then get back the house chores. It was all according to the law of branch and root. But in our world, people tried to follow the external form of the Torah instead of observing it not only externally but internally as well.
The Torah, “Leviticus” (Metzora), 15:29: And on the eighth day, she shall take for herself two turtle doves or two young doves, and bring them to the Cohen, to the entrance of the Tent of Meeting.
A purified woman takes her corporeal desires and raises them to the level of the Cohen (priest), the level of Bina. In that case Malchut rises to Bina and is ready to receive the Upper Light. It is ready for the next level.
