That led to looking up what 30 Rock is, because I like that TV show. In this reference though, 30 rock is a nickname for the GE building, from its address, 30 Rockefeller Plaza.
It turns out that Ancient of Days is another name for God but that different traditions have different meanings. This was my chance to look at all the names for God, but instead I jumped to Esotericism because it sounded interesting and that group has a different interpretation on Ancient of Days.
Esotericism, as Wikipedia reports it, largely overlaps with "hidden knowledge."
Gnosticism and its hidden knowledge aspect seemed to be too easy a choice so I took the Hermeticism branch instead and fell right into a discussion of Hermes Trismegistus who may or may not have existed but is suggested as the founder of a whole system of beliefs of which The Order of Freemasons and Rosicrucianism are based.
Let's stop here.
My theory is that Wikipedia and the Internet it is a part of are either schizophrenic themselves or are conducive to schizophrenia. My innocent clicking of links led me deeper into an alternate world of secret religions and hidden knowledge and farther from rational discourse and reality. I am lucky that I don't hear voices in my head right now. Maybe the real secret is that there is a conspiracy to make people believe in conspiracy theories and secret societies all of which may or may not exist. I call it the meta-conspiracy theory.
