The partzufim can be divided into the partzufim of the first three, which are the partzuf of Keter, the partzuf of Ḥokhma, and the partzuf of Bina, and into the partzufim of the six extremities, which include the partzuf of the lower seven sefirot of Bina, which is called Yisrael Sabba and Tevuna, the partzuf of Ze’er Anpin, and the partzuf of Malkhut. These latter three partzufim are always considered the partzufim of six extremities, and even when they receive the first three, they do not leave the aspect of six extremities.147There are situations in which these partzufim of the six extremities become connected to a set of the first three sefirot, but they still retain their status as the partzufim of six extremities.
