kaitsereiim
Kaitsereiim is a term that appears in some interpretations of ancient Jewish mysticism, specifically within Kabbalistic literature. It is generally understood to refer to a type of spiritual guardian or celestial entity. The exact nature and function of kaitsereiim can vary depending on the specific text and tradition, but they are often described as being responsible for protecting certain divine realms, overseeing cosmic processes, or assisting in spiritual ascents.
The word itself is a composite, often broken down into "kaits" (meaning "summer" or "heat") and "reiim"
