Since Coupling is the goal of all service, we will conclude this entire discussion with an explanation of the order of Coupling.
According to the order of Coupling… The entire order starts with the very first preparation for Coupling and continues until the whole act is complete.
…Nukva – the Shechinah – must encompass all the lower worlds. You have already heard that Nukva is the root of all the lower creations and is therefore incomplete without them. Accordingly Nukva must first contain within her all these lower creations – in the sense that they must be bound to her in all the ways prepared and ready to bring about these interconnections. The way in which the worlds become bound to and contained in the Shechinah is through the Chambers (היכלות, heichalot), which ascend and become bound with each other until everything is contained in the Chamber of Holy of Holies of Beriyah. There they are all bound with the Shechinah like branches merged in their source.
