Since the body is so despicable, it is doomed to perish and to be buried.
What does it mean,“doomed to perish” and “to be buried”? By the body, we mean desires from the moment of birth, because they have egoistical intentions. “Doomed to perish,” means to be completely cut off from the light, become dead. The person considers his “desires with egoistic intentions” to be dead. He is neither able nor willing to use them, wants to bury them. After that, the desires go through corrections, i.e., the intention for one’s own sake (which is the intention of the Klipot) is transformed into the intention for the sake of the Creator, for the sake of bestowal. This process is called a resurrection of the dead bodies.
