…with all the different aspects of service they contain… The Shechinah is not only the root of the lower creations themselves but of all their different aspects – including especially the task entrusted to them. For since the repair is in their hands, they have to carry out their function – which as part of their essential nature must also be rooted in the Shechinah.
…that of the angels and that of the souls. These are two kinds of branches, each with its own exclusive task.
The function of the angels is to execute the commands of the Shechinah… The angels merely execute the actions of the Sefirot – because the Supreme Thought also wanted this gradation whereby the actions of the Sefirot and the creations subject to them should not issue directly from the Shechinah but through these agents that she has. Theirs is not the service of free will but literal servitude.
