What is the religion where a five pointed star inside a hexagram which is a pentagram with a star of david instead of a five pointed star is filled in with letters to perform a specific event?

The description you provided resembles practices in certain forms of ceremonial magic or esoteric traditions, often associated with occult practices rather than a mainstream religion. Such symbols can be found in various magical systems, including those influenced by Kabbalah, where the Star of David and pentagrams are employed in rituals. However, there isn't a specific religion that exclusively uses this particular combination of symbols as a recognized practice. Instead, it reflects a blend of mystical and symbolic elements from different traditions.
