Having explained the location of the governmental order arising out of this interconnection of MaH and BaN, we will now consider it in more detail and discuss the uncertainties contained in the Unknown Head.
The proposition consists of two parts: Part 1: All the different kinds of connections... This explains what is contained in the Unknown Head as a result of the way MaH and BaN join together. Part 2: The way these combinations rule above... How this affects the Partzufim.
Part 1: All the different kinds of connections that could possibly exist between MaH and BaN... This whole subject relates to the “uncertainties” (ספקות, sefeikot) discussed by the ARI of blessed memory in connection with the Unknown Head. These are uncertainties relating to the way MaH and BaN are joined (see Etz Chayim, Shaar Atik ch. 3ff). There are two apparent difficulties about these teachings. Firstly, of what benefit is it to know what these uncertainties are? Secondly, the ARI himself says – and it is necessarily the case – that just as there are uncertainties relating to the Unknown Head, so there are uncertainties in all the other Partzufim (ibid. ch. 5). If so, one could ask what reason there is to call this Head specifically the “Unknown Head” when all the rest of Atzilut is likewise unknown.
