The desires called Ammonites or Moabites cannot be corrected in the form that they exist. They can be corrected only through death. It means that a person completely annuls his egoism.
In other words, all ten Sefirot are in the impure area, in receiving for one’s own sake, and in such a form that they can’t be corrected; hence, they must go through the complete annulment of intention. This is death. In the wisdom of Kabbalah, all that goes to bestowal is called life, and to reception, death.
Therefore, all the desires that are called seven nations of the world cannot be corrected. We only can kill them within ourselves, and only once their egoistic use completely ceases can we begin converting them to altruistic use.
