The famous Kabbalist of the XVI century Ramak wrote in the book Ohr Yakar that people studying The Book of Zohar awaken forces of the souls of the righteous together with the force of Moses. After all, a person who studies The Book of Zohar is in connection with the source of the upper light, with the force of bestowal and love. Therefore, he passes the upper light through him to all the souls that are below him.
There is a point in each of us that distinguishes him from others. It is within this point that he is the only one above all the others. This is how each of us passes the upper light through him to all other souls.
Therefore, we do not need to change the world. By changing himself, a person changes everyone else because he is in connection with them.
