And this is the secret that during the weekdays there is no coupling, and the coupling is forbidden: for the six weekdays are in Yetzira, the secret of Metatron. Therefore, in the ZON that are in it there is no coupling in them, for they have no Mochin; hence there is no coupling during the weekdays. And this is what is said: "six Sefirot nest in Metatron." Explanation: that ZON of Atzilut give to Yetzira only its own light of six Sefirot, what it had from its beginning; but from the secret of the Mochin that come to it as an addition, it does not give them. And this is the secret of "they nest in Yetzira." And the matter is that through the couplings, souls and holy spirits and angels come out and are drawn to Yetzira, to grow there in the secret of the six extremities alone; and all this is through the face-to-face coupling of Atzilut.
