The twelfth Correction (formation)
Synopsis
Rabbi Shimon explains to Rabbi Yehuda that the hairs around the mouth of Arich Anpin are cleared away so that the inhalation of Zeir Anpin will not be interfered with, as the breath comes from the uppermost holy mouth. The breath that comes from the mouth of Arich Anpin splits up into 37,000 directions and clothes whoever is deserving of being clothed by it, "As You have sworn to our fathers."
