Answer: The mind is the Light of Hochma (Wisdom), which I attain when I bring myself from the side of my desire, Malchut, to correspondence with the first nine Sefirot.
Malchut is a receiving vessel, the will to enjoy. If I change it to bestowal, embodied by the first nine Sefirot, I turn it into a vessel for the Light of Hochma. This is called the mind, the Light of Wisdom (Hochma), that is dressed in the creature’s desire.
We cannot attain the upper mind with our corporeal mind. The upper, acting mind is the mind of the Creator, Who created the created beings with the Light of Wisdom. We can attain it only through equivalence of form, as we correct ourselves.
If I correct my desire to receive to bestowal, that is, I fill it with Light of Hassadim (Mercy), I acquire the anti-egotistic screen with which I perform a union with the Light (Zivug de Haka’a), thus raising the Reflected Light. Then the upper Light clothes me, and I attain the mind of the Creator.
The wisdom of Kabbalah is called the “wisdom of reception” since it teaches us how to receive the Light of Hochma and thus attain the Creator. However, we attain this mind gradually, according to our equivalence to Him in bestowal. It is not the corporeal, beastly mind we are born with.
We obtain the upper mind due to our correction. The more a person corrects himself, the greater spiritual mind he attains. It has nothing to do with one’s inborn mental abilities. One can be Einstein, but it will have no effect on his or her spiritual advancement.
The corporeal mind that helps a person understand how to better use his egoism has nothing to do with the mind he acquires namely by lowering himself, the work in the group, meaning thanks to actions that are seemingly senseless, irrational, and scorned by everyone.
