However, this occurs only in the holy partzufim of Atzilut (Emanation), Beria (Creation), Yetzira (Formation), and Asiya (Actualization), but not in the partzufim of the kelippot nor in this world, in which the fourth level itself serves as the receiving vessel. 20Generally the fourth level constitutes the fully developed form of the will to receive. Therefore, it is separated from the Creator, since it is the opposite in form from that of the Creator in the sense that He is the ultimate giver and has no trace of the attribute of receiving.
In the higher worlds of Atzilut, Beria, Yetzira, and Asiya the fourth level is tempered with some of the attribute of giving through the fusion through collision described above. However, the partzufim of the kelippot mentioned here represent creations and beings that operate within the plane of the fourth level, which means they are formed solely within the realm of pure receiving and so are totally separated from the Creator.
In these contexts, such creations are unable to interact with or receive the supernal light, since, in their receiving nature, they are fundamentally opposite to the pure giving nature of that light. Therefore, they are separated from the supernal light, as the difference in form of the fourth level from that of the Emanator, which is the attribute of giving, separates them from each other. Consequently, the kelippot, and similarly the wicked, are regarded as dead, for they are separated from the Source of Life, who bestows life, by the will to receive within them, as mentioned in section #13# above. See the description there in detail, as it cannot be explained any further.
