The sum of the matter is that Zeir and Nukva derive from Imma’s Strengths, which are female. Initially Zeir Anpin’s power is therefore not like that of a male but weakened like that of a female. Coupling – which channels the light through the entire chain of development – would then be highly dangerous, because excess influence improperly channeled gives nourishment to the unholy forces. Accordingly Zeir and Nukva look each other in the face so as to reveal their powers in the full sequence of cause and effect only when the influence flows after all due preparation and with goodwill.
Instead all that is seen are the female aspects, which the Male and Female use together in one surge of excitation – yet both of them are still fully closed up. Until Abba and Imma come and repair Zeir Anpin, distributing the powers in the proper way with Kindness alone on one side and Strength alone on the other. All the female aspects are now left exclusively to Nukva while all the male aspects are renewed in Zeir Anpin. He then receives the power to sweeten and repair the Nukva as well by Coupling, as will be discussed presently.
