I literally cannot get over the religious allegory in Severance. More specifically how the Eagan handbook and The YOU you are by Ricken are presented as opposing religious texts in the innie world. Like The YOU you are is so incredibly important to Mark's innie while being something that outie Mark wouldn't even open is just so poignant. I love the idea that while Ricken is for sure a weirdo he also has ideas that are transformative for the right crowd.
His book is redundant in the outie world because it contains things an outie is already aware of (and some things that an outie would know are false depictions of history). Mostly sense of self and relationships. But an Innie has no prior info on how any of these social/personal conventions are supposed to work except what they are fed by Lumon so a book full of drawn-out explanations of what it means to be a person and what it means to have relationships with other people would in fact change an innie's life enough to warrant a religion-like following of the book. Much like how the Handbook functions for Innie's like Irving.
