Now, we will bring the language of the holy Rabbi, of blessed memory, from the writings on the intentions of the Tzitzit, specifically in the second discourse:

"And now, understand the matter of the hairs of the head of Ze'ir Anpin (Z"A): Know that in the head of Z"A there are three types of hairs, and they correspond to the three stages of development in Z"A: the initial stage of gestation, the stage of nursing, and the stage of maturity. The explanation is that we have already clarified that there are three stages in Z"A, and they are gestation, nursing, and maturity. The first stage of gestation and nursing are the states of smallness (Katnut), while the state of maturity is the state of greatness (Gadlut).

And when the mature intellects (Mochin) come into the head of Z"A, they are called by the names of the Tetragrammaton (YHVH) in their expanded forms. However, the Mochin of smallness are expelled downward, and their illumination ascends from below to above, but only their illumination, not their essence, which remains below. Yet, their illumination returns in the secret of the surrounding light (Or Makif) and the Mochin of smallness are indeed expelled downward, but their illumination returns to grow the hairs.

The hairs begin to emerge from the head and continue to grow even during the time of maturity, even though the Mochin of smallness are expelled downward at that time.

The Rabbi continues: The hairs grow from the three types of Mochin found in Z"A's head. The first type is strong and comes from the Mochin of gestation, the second type is softer and comes from the Mochin of nursing, and the third type is the softest and comes from the Mochin of maturity.

The reason for this is that the hairs are the letters of the word "Sha'ar" (שער), which is numerically equivalent to ten, corresponding to the ten letters of the expanded Tetragrammaton (YHVH). In each of the expansions, there is one letter 'Yud' (י), which is the first letter of the Tetragrammaton, representing the concept of the hairs.

The name "hairs" is given because they are from the Mochin of maturity, which are the names of the Tetragrammaton in their expanded forms. The word "Sha'ar" (שער) is composed of the letters of "Ra'ash" (רעש), indicating the dynamic nature of these spiritual processes.
