Why is "Mysteries of Osiris" trending?

Wikipedia Overview

The Mysteries of Osiris, also known as Osirism, were religious festivities celebrated in ancient Egypt to commemorate the murder and regeneration of Osiris. The course of the ceremonies is attested by various written sources, but the most important document is the Ritual of the Mysteries of Osiris in the Month of Khoiak, a compilation of Middle Kingdom texts engraved during the Ptolemaic period in an upper chapel of the Temple of Dendera. In Egyptian religion, the sacred and the secret are intimately linked. As a result, ritual practices were beyond the reach of the uninitiated, as they were reserved for the priests, the only ones authorised to enter the divine sanctuaries. The most unfathomable theological mystery, the most solemnly precautionary, is the remains of Osiris. According to the Osirian myth, this mummy is kept deep in the Duat, the subterranean world of the dead. Every night, during his nocturnal journey, Ra, the solar god, came there to regenerate by temporarily uniting with Osiris in the form of a single soul.
