Kabbalah su II Samuele 22:9

The nose of Arich Anpin
The breath (or spirit) of life blows on Zeir Anpin through the nose of Arich Anpin, through the opening of this orifice. One Hei derives from this orifice that supports another Hei below. This breath emerges from the hidden brain and is called the spirit of life. By means of this spirit people will know wisdom at the era of King Messiah, as written, “and the spirit of Hashem shall rest upon him, the spirit of wisdom and understanding…” (Yeshayahu 11:2). This nose (chotem) is life in every direction, complete joy, contentment, and healing. It is written of the nose of Zeir Anpin, “there went up a smoke out of his nostrils” (II Shmuel 22:9), but here it is written, “and for my praise will I refrain (echetom) for you” (Yeshayahu 48:9).

According to the Book of Aggadah from the academy of Rav Yeva Saba, Hei, which is Malchut, is established by receiving from the mouth of Arich Anpin. But here, with regards to this discussion, this is not so relevant, and Malchut is not connected to the mouth of Arich Anpin but to the left nostril in the nose. Even though it amounts to the same thing, judgment derives from Hei, since it is the aspect of lower Chochmah that shines with judgments (as in the Greater Gathering, section 219); judgment also derives from the nose, that is, from Chochmah that is bestowed by the nose, as written, “there went up a smoke out of his nostrils”. You may argue that “fire out of his mouth devoured” (II Shmuel 22:9), meaning that there are judgments in the mouth as well. He answers, anger derives mostly from the nose, since Chochmah flows from there.

The nose of Zeir Anpin
The nose of Zeir Anpin completes the face, it makes the face recognizable. This nose is not like the nose of the most hidden Atika Kadisha. The nose of Atika is the life of the living; the spirits of life come from the two nostrils. Of this Zeir Anpin it is written, “There went up a smoke out of his nostrils” (II Shmuel 22:9).
