“When you build a new house, you shall make a guard rail for your roof, so that you shall not cause blood [to be spilled] in your house, that the one who falls should fall from it [the roof]. “(Devarim 22:8)
The Ramchal explains to us that the secret of the partzuf of Nukva is rebuilt anew on Rosh Hashanah is alluded to in our pasuk therefore all the residents of this world pass like sheep before Hashem on this day to be judged for their actions and to see how Nukva can be rebuilt to guide and lead them all year long.
As soon as she has been built up into a new structure and edifice, we must draw around her the surrounding lights called Oros Makifin in order that the external forces of darkness cannot grasp hold of her with their evil clutches.
Therefore, we build a Sukkah right after Rosh Hashanah [and Yom Kippur] to achieve this surrounding light and protect the partzuf of Nukva from the chitzonim. This final building is only completed on Shemini Atzeres.
Therefore, Chazal say the zman of Sukkah lasts all seven days since so long as the edifice is not finished being completely built we can draw around her the oros makifin of the Sukkah to surround her with protective light. Our pasuk says “when you build a new home,” which is the secret of rebuilding the Nukva and then immediately “make a guard rail for your roof,” the roof is the secret of the three supernal attributes the sefiros that have the primary protection, “so that you cause no bloodshed in your home,” and prevent the external forces of evil from entering the edifice so that no one “should fall from there.”
The Ramchal explains further on the pasuk “Bais Yaakov lechu ve'nelcha BeOhr Hashem,” in (Yeshaya 2:5): All the souls and celestial lights are all surely contained within the Shechinah, therefore She is known as Bais Yaakov since Hashem places all into Her hands and She guides them all the higher and lower beings – elyonim ve'tachtonim.
She is compared to a house, like a Bayis where people place within their homes whatever they need and want, so is the Shechinah like a Bayis – a home where Hashem places all the soul and celestial lights of the higher and lower beings. Everything is handed over to Her and She guides all the creations and creatures of all the worlds based on how man operates. . .
The Shechina leads and guides all of our souls to completion and perfection so we can all leave the exile and go out of golus and the redemption of geulah can arrive. As Chazal say: Ben Dovid – the Moshiach cannot arrive until all the neshomos of the guf cease arriving. They are called collectively known as Bais Yaakov since Yaakov alludes to katnus – immaturity and small-mindedness however our positive actions help them reach gadlus – maturity and expanded consciousness – that is why the pasuk says – Bais Yaakov lechu – go out of golus for redemption, leave katnus behind and be repaired through the tikkun of gadlus. Then once repaired we can walk together beOhr Hashem - in the light of G-d.
