According to the order of Coupling, Nukva – the Shechinah – must encompass all the lower worlds. These must be properly repaired in all the necessary ways – through the removal of the Other Side and the repair of the worlds by each other through all their good arrangements. Nukva is then ready for Zeir Anpin, and he joins with her. He then gives her a certain power known as “the Spirit that her husband sends into her”.
Through this power she sends up Female Waters – this being what she channels – whether in the form of a revelation of new light or through the restoration of what was concealed or damaged. She sends up her Female Waters through the power of the souls of the Tzaddikim. Zeir Anpin then increases what he gives her – in proportion to what she sends up – in the form of new influence, this being the Male Waters.
This afterwards descends into the world, spreading to the ministering attendants and from there down to the world of Asiyah, from where it goes forth to act.
