Except that when we observe the differences found in the Partzufim... For the differences are visible in the Partzufim....in various different states and certain other changes that take place in them... For sometimes lights and repairs are seen to hold sway in the Partzufim and sometimes deficiencies. These are the changes in the states and functioning of the Partzufim as discussed in the teachings of the ARI of blessed memory in connection with these uncertainties....we know that these derive from the way MaH and BaN are joined. The Unknown Head is the root of all this – i.e. these changes derive from there.
