Kabbalah su Esodo 34:7

We learn from this passage that even if the harm [caused by] error is great, it nonetheless appertains only to one who is unqualified to teach and [yet] teaches. However, [with regard to] the subject of teaching oneself, there is no harm at all stemming from error. On the contrary, [such a person] receives a reward—though not as great a reward as that [given to] one who arrives at the truth. The difference between them is similar to that between the barren tree and those trees which bear fruit. Thus holiness increases and bears fruit in the light which emanates from the true Torah of one who knows its secrets and continually teaches them. The same [holds] for the other divisions of the Torah. There is no doubt that [such a teacher] will cause an emanation, and that this emanation and light which is created [through the teaching] will abide forever, bearing fruit for himself and for generations [to come]. Thus it is written, He keeps mercy to the thousandth generation (Exod. 34:7). He retains [His] mercy to a thousand generations with regard to the merit of the fathers and similar things. The essence of the good deed, which constitutes the essence of the light, is kept for him for the world-to-come, where he sits and enjoys [it].

The unknowable head extended a single sway that is included in the forehead
That concealed unknowable head at the head Atika, that is, the first head, extended a sway that is prepared to shine, then used it to strike that brain, concealed Chochmah of Arich Anpin, which was engraved, namely, reduced to the phase of immaturity. It then received maturity as well by that sway and scintillated with many lights, both with Chassadim and Chochmah. Concealed Chochmah produced its illumination and marked this conclusion on the forehead. Another light that is called will was marked on the forehead, and the will spread down the thirteen features of the beard of Arich Anpin, down to where it settled in the beard that is called supreme Chesed. This is the attribute that is called “keeping troth (Chesed)” (Shemot 34:7), the eighth of the thirteen features of the beard. When the will is revealed by this attribute, judgment bearers behold it and surrender.
