Two kinds of Chochmah, concealed and revealed All the implements of Atika Kadisha were installed in the silent and concealed brain, that is, concealed Chochmah; whereas all the implements of Zeir Anpin were installed in the lower Chochmah, that is, in Binah that reverted to Chochmah upon returning to the head of Arich Anpin, though not in actual Chochmah, as said, “in wisdom have you made them all” (Tehillim 104:24).
And Hei, Malchut, surely includes all, since Malchut is where Chochmah is revealed. What is the difference between Hei, lower Malchut, and Hei here in the left nostril of the nose of Atika? Judgments awaken from the Hei here in lower Malchut; but the Hei here in the nose is mercy within mercy like the left eye of Arich Anpin, which is white within white (as said in the Greater Gathering, section 42; study there).
Similarly, even though the hair of Arich Anpin originates in concealed Chochmah, it is white because concealed Chochmah is establish as one within the other (as said in section 37).
