These ten levels are associated with Kabbalah's (Zohar) four different "Worlds" or planes of existence, the main part from the perspective of the descending "chain of progression" (Seder hishtalshelus), that links the Infinite Divine Ein Sof with the finite, physical realm. In all Worlds, the 10 sefirot radiate, and are the Divine channels through which every level is continuously created from nothing. Since they are the attributes through which the unknowable, infinite Divine essence becomes revealed to the creations, all ten emanate in each World.
