Answer: The quality of work depends on what kind of Light I receive from my equivalence to the Creator: Nefesh, Ruach, Neshama, Chaya, or Yechida.
We must go through 125 spiritual degrees to complete similarity with the Creator. The similarity lies in my love for others. It turns out that I must achieve precisely the exit from myself in the unanswered, unselfish, and absolutely unearthly love of others, meaning in caring for others.
Love in Kabbalah is a state where I feel the desires of another person and want to fulfill them completely, as if they are my biggest and most important desires.
All my nature, my whole essence, and all my inner self I dedicate to the service of other people’s desires. Therefore, this condition is called spiritual slavery.
