Answer: By teaching my students, I rise accordingly because I am disseminating this wisdom. And every potential small soul joining the common development connects to the general course of correction and affects everyone.
In other words, I affect the common soul of Adam by including you in it through me. Thus, I impact the whole universe.
Question: So, you are clearly interested in advancing?
Answer: I am obviously interested in all of you advancing. However, this interest is not selfish or egoistic because I personally want the whole system to reach adhesion with the Creator. There, the ego completely vanishes. Your question makes no sense because in Kabbalah the particular and the collective are completely equal.
