A question I received: What are angels and other spiritual creatures mentioned in the Torah?
My Answer: All Kabbalistic books mention Ofanim, Hayot, and Kruvim. It says in The Zohar (Beresheet, item 77, page 81): “Ofanim are angels of the World of Assiya, Hayot are angels of the World of Yetzira, and Kruvim are angels of the World of Beria.” They all represent a small Light (Vak de Hochma) in each world, and they depend on the human souls. For example, when a person corrects himself, then Kruvim face each other, as it says in the Torah.
There are also spiritual forces that are referred to as lion, ox, eagle, and man; they correspond to Sefirot Netzah, Hod, Yesod, and Malchut. In addition, Kabbalistic books sometimes refer to different levels in the spiritual worlds by the words South (Hochma), North (Bina), East (Zeir Anpin), and West (Malchut). And there are many other terms.
All of this speaks only about the state of the Light in the Kelim (desires) according to the law of equivalence between them – to the degree that the Light and Kli share the property of bestowal, which is attained through our efforts. Instead of getting lost in all these names, I advise you to start using Kabbalistic (scientific, physical) terms, such as Sefirot, Olamot, Masachim, Partzufim, Reshimot, Orot, and etc. After all, no matter how you look at it, not one word in Kabbalah speaks about our world. All the confusion only wears a person out and takes him away from the goal.
