In its early 12th-century dissemination, Kabbalah received criticism from some rabbis who adhered to Jewish philosophy, for its alleged introduction of multiplicity into Jewish monotheism. The seeming plurality of the One God is a result of the spiritual evolution of God's light, which introduced a multiplicity of emanations from the one infinite Divine essence. This was necessary due to the inability of mankind to exist in God's infinite presence.[5][6] God does not change; rather, it is our ability to perceive His emanations that is modified.
