The forehead of will of Arich Anpin The forehead that appears in Atika Kadisha, that is, in Arich Anpin, is called will. This highest head, which is concealed on high, being unknown, extended a sweet and comely sway that became a part of the forehead. And since the will of all wills is established in the forehead and appears by decision, this forehead is called will.1These Chassadim are much more elevated than Chochmah because they contain both their virtues.
By bestowing Chochmah upon Zeir Anpin, they are considered as being like Chochmah themselves. They can subdue the external forces just like Chochmah; but being Chassadim, the external forces have no hold on them. The light of Chassadim does not thicken at all as it descends to terrestrial beings; for the tzimtzum applies to the light of Chochmah alone, not the light of Chassadim.
