Here lies the answer to an apparent difficulty about these worlds of Vision, Hearing, Smell and Speech, which appear not to follow the order of the rest of the Tree. The world of Beriyah, for example, emerges from Atzilut in the sense of being a single continuation of it, emerging like a seal stamped with all the Sefirot of Atzilut, which pass through a screen. Each Sefirah in Atzilut actually brings forth the corresponding Sefirah in Beriyah.
Yetzirah emerges from Beriyah in the same way, and similarly Asiyah from Yetzirah. It is therefore fair to say that they are one under the other, for they emerge one from the other. Similarly in the case of the Partzufim: Abba and Imma emerge from Arich Anpin through the process of internal coupling (זיווג, zivug) within, while Zeir Anpin and Nukva emerge from Abba and Imma through their coupling.
This is not the way in which the worlds of Vision, Hearing, Smell and Speech emerge from Adam Kadmon. Rather, these emerge from within through the sensory organs.
