I have been reading the Saadian version of the Sefer Yetzirah quite a bit. It isn’t long at all so it is easy to read it once before bed or sometime in the evening. Not quite every night, I sit down to contemplate through some piece of it. If I want to look at just one section and absorb it, I tend to read either Chapter 1 and Chapter 4.
Following on the last post, let me talk a bit more about what I mean when I say that the Sa’adia diagram might provide the basis for a better ontological account of what exactly is going on with the talk of qlippoth. If we look at the tree as a manifestation of the archetypal forces of creation interacting with an alien matrix that receives it (which isn’t Sa’adia’s point, but one to which his model well extends), then the alien matrix’s own being has to be taken into account. Far from a passive mirror, it responds to the archetypal forces of creation according to difficult to discern internal properties of its being.
On some level, if for no other reason than they are capable of interacting, we can grasp that there is a deep affinity between archetype and matrix. There are many dimensions to the matrix just as there are many dimensions to the archetype. Whether as a result of the interaction with the matrix, or on the basis of its own self-differentiation, the archetype manifests such that it develops multiple points of reflection on itself, the seeds of individual souls. Those seeds possess the same constituting properties of the archetype on a smaller scale.
