Even what is seen is not the actual divine powers themselves. This is obvious. For whoever wants to know these powers in their intrinsic essence would have to know Godliness in its intrinsic essence, because the Sefirot are pure Godliness. Since the essence of Godliness cannot be known at all, it is also impossible to know the essence of the Sefirot. Whatever is known of the Sefirot is only because it is permitted to see them in this way, not because they are this way intrinsically. What is known of them is this spiritual form. This spiritual form is not their intrinsic essence but only the form in which they are permitted to be seen.
