Question: What is the “revival of the dead” according to the wisdom of Kabbalah?
Answer: In Kabbalah, the revival of the dead means the revival of dead desires. Desires are called dead if they are egoistic and alive if they are altruistic, i.e., are working with an intention for the sake of bestowal. When lifeless, dead, egoistic desires become living, altruistic desires, this is called the revival of the dead.
