The proposition consists of three parts. Part 1: The Sefirot can appear... This explains how the images change. Part 2: Each likeness seen... This explains the utility of these changes. Part 3: The attributes and powers... This explains the difference between the images and what they represent.
Part 1: The Sefirot can appear in likenesses that may even be mutually contradictory... If the likenesses through which the Sefirot appear were intrinsic to the Sefirot themselves, it would obviously be impossible to attribute two contradictory likenesses to one and the same subject. However, since these likenesses are not intrinsic to the Sefirot but were chosen by God, there is no difficulty in the fact that they may appear in different and contradictory likenesses, one after the other, or even simultaneously. For at one moment the Supreme Will wants them to appear in one way, and the next in a different way.
