Men’s service and all that they receive are bound up with this central Tree, the Name of HaVaYaH, which is garbed in the Partzufim. Afterwards they also attain the worlds in which this Name is clothed, for they inherit them as a matter of course when they inherit the One clothed in them.
As I have already said, this Tree extends from the head of Adam Kadmon to the end of Asiyah. In essence, this Tree is Adam Kadmon and the radiance that emanates from Him. For a glorious radiance came forth from Him, and the different parts of this radiance constitute the worlds of Atzilut, Beriyah, Yetzirah and Asiyah. It is through these very worlds that He shows what exists above. Just as there are many kinds of worlds above with one central world inside them all, similarly, a single order is visible within the worlds of Atzilut, Beriyah, Yetzirah and Asiyah. This is the order of the Name of HaVaYaH, blessed be He, standing in the form of Ten Sefirot, while many other orders stand in the form of the Chariot. These other orders are included in the four Chayot and their four faces and all the other aspects of the Chariot.
