Part 7 · Chapter 18

Indeed, you should know that when these dross were sorted and their four worlds ABYA were made of them, they are complete dross and shells. All the phases of Melachim [kings] that could not be sorted were placed inside them as the Neshama and vitality in them, which sustains them, as mentioned in the portion Yitro p 69, “There is no Sitra Achra that does not have a thin light.” This is the meaning of the pursuit of the evil inclination and the Sitra Achra to make the righteous sin and cling to the holiness, as they have no vitality without it. When the Kedusha [holiness] and goodness increase, their life increases. Now you should not wonder why the evil inclination is in pursuit of Adam to make him sin.
