By the Head of Arich Anpin is meant Kitra, the Crown, and Chochmah S’tima’ah, the Concealed Wisdom contained within it – this is in terms of what is attributed to Arich Anpin’s own intrinsic mode of government. The Seven Repairs of the Head are found in Arich Anpin, and this is because the entire government of Arich Anpin depends upon Atik. For this reason the seven lower Sefirot of Atik rule in the Head of Arich Anpin through the various particular repairs therein deriving from Atik. In the Skull they function generally, while in the Face they operate in detail, because the Face is made to shine in detail and all its radiations must be rectified through the repairs deriving from Atik.
