Answer: To the extent that I annul myself, I give myself a chance to receive from the upper force, thoughts, attributes, and desires correctly instead of my self-powers, thoughts, attributes, and desires. In fact, I change my form. But the new form is so different from the old form that it is as if I totally change myself.
In fact, only my values and my perspective change, but it seems as if I become a totally different person.
The prayer, MAN, means that a void has been created in me, a deficiency for the attribute of bestowal, instead of old desires to receive I had before. I don’t know what bestowal is and what it should be like so that it can take the place of the desires I have restricted, but I want that a new heart will enter the void I have prepared for it, a new mind. This means that I raise MAN, a prayer, by making room inside my desire to receive for the new use.
Then in response, I receive MAD, the force of overcoming. So this answer from Above is called Mei Dechurin. In addition to the force, I receive a mind, since I begin to weigh to what extent I can work with this force of overcoming, in order to build the head of my spiritual Partzuf and to resemble the upper.
I already identify the upper and understand how I should work in order to act like Him. It is of course not much in the meantime, just like a small child who tries to resemble a grownup, but this is how we learn.
