…is from the two Mazalot of Notzer and Venakeh… These two comprise the entire governmental order, and accordingly, the totality of the spreading influence.
…by way of the Palate and Throat… The flow is not channeled directly from the Mazal of Venakeh to Abba and Imma but enters into the Throat. The reason is that the Throat of Arich Anpin is Keter of Abba and Imma. (“Binah of Arich, which is in the Throat, becomes two crowns for Abba and Imma” – Etz Chayim, Shaar Arich Anpin ch. 2.) The flow must enter there in order to go into their interior. For this reason, when the light reaches the Mazal of Venakeh (the overall receiver of the 13 Repairs of the Beard), it returns, enters the Throat and from there goes to Abba and Imma. In entering the Throat it must pass by way of the Palate, which is the male aspect, i.e. Chochmah (of Binah), in relation to the Throat, which is Binah (of Binah).
