Even the Hairs of the Head Hold Kabbalistic Secrets

…of the holiness of the Brain… The number of strands of hair in the locks of the Head corresponds to the numerical value of the letters of the word קדוש, kadosh, “holy” – 410, as explained by Rabbi Shimon bar Yochai in the Idra Rabba (128b): “Every lock consists of 410 hairs…” This is because it is through the Hairs of the Head that the holiness of the inner Mental Powers flashes forth to be revealed on the outside. …just as it is within. Even when drawn forth, it does not change.

Part 2: However, the Beard is such that its lights descend in sequence, level by level... The reason that the levels of the Beard are enumerated individually (as 13 Repairs corresponding to the 13 Attributes of Mercy) – in contrast to the Hairs of the Head – is because the levels of the Beard are involved in the mystery of the interaction and coupling of the two attributes of Notzer (נוצר), “…Preserver of Kindness…” and Venakeh (ונקה), “…Who cleanses…” (Exodus 34:6). These are the two Mazalot or “Constellations”. (The eighth and thirteenth of the 13 Attributes of Mercy include all the others. “These two Mazalot rest one over the other and are male and female” – Etz Chayim, Shaar Arich Anpin ch. 9.) They interact and couple together, the purpose being to draw down the lights in proportion to the power of the two parties to the interaction. For it is in the brains of the couple that the light emanated through them is drawn down. In this way the light descends to the same level as that of the couple, and it is on this level that the light is emanated. (It is through coupling – זיווג, zivug – that they draw down the light from above. Since it is the two parties in the interaction that draw down the light, what they draw down is on their level, and this is how the developmental chain of the Partzufim descends level by level. In the case under discussion, the two parties in the interaction or coupling are Abba and Imma, which are included under the Mazalot of Notzer and Venakeh respectively, which transfer the lights of the Head of Arich Anpin to Zeir Anpin.)
