The entire government of the universe is ordered under the four letters of the Name of HaVaYaH
The first order assumed by the emanated light, standing in the form of Ten Sefirot arranged in the Likeness of Man, is called Adam Kadmon. This is the order of the Name of HaVaYaH, blessed be He for ever and ever. This means that all the different orders and laws are drawn after and come under the order of these four letters. In accordance with this order, the teachings of the Kabbalah always trace everything to the underlying foundation of the four letters of the Name, blessed be He.
