God revealed the 13 attributes (Exodus 34:6,7) to Moses after the sin of the Golden Calf. They allowed connection to the supernal channels of pure light of Chassadim, drawing light of mercy to cleanse the nation from the sin.
We recite these attributes when we wish to connect to the highest level, during holidays and when during the Slichot, when we ask to be cleansed from our inequities.
From the concealed Chokmah in the Keter of Atik come out hair to the right and left of the ‘head’. The Zohar use the word ‘hair’ to represent thin channels of light that come down from the head, which is Keter. They are narrow in order to restrict the light of the Endless. They go down the two sides of the head to represent lights spread to Right and Left columns.
The roots of the hair are in קרומא דאוירא Da’at of Atik that connects Keter of Arich and Chochmah of Arich. The hair come out from the Chochmah of Arich, (מוחא סתימאה, concealed). The split between right and left create the aspect of judgment for the first time.
From Atik, which is Arich Anpin, come out supernal Father and mother, which is Chokmah and Binah of Atzilut.
The light to all the worlds and sefirot below comes from this level.
Keter of Arich Anpin includes the three ‘heads’ that we studied previuosly. They are teh seed for the three columns that would ‘manifest’ below.
