Answer: The method of Kabbalah is intended for the correction of our evil inclination, meaning the corrupt desire that is entirely directed to its own benefit, instead of bestowal to another person. This correction helps us to become similar to the Light, to the Creator. According to the similarity of form, the Light becomes clothed in a vessel, and then we sense the upper reality.
Question: What happens in the relationship among the friends when I feel envy or hatred?
Answer: Despite the vices being revealed, you keep going and try to unite with your friends above this corruption. There is nature, but we must be above it. This is how we correct ourselves. We are not destroying the egoism, but we are working above it.
I cannot stand my friend, and I do not wish to interact with him. However, I am trying to connect with him above this rejection.
After all, this rejection is the result of my corrupt, egoistic desire. With my purpose being correction, I try to rise above it and treat my friend in the opposite way, with love.
Both of these forms coexist within me. I recognize my rejection, and, at the same time, I decide to express a different attitude, seeing my friend as a great person.
This is our work.
