Livre d'Or

everybody thinks that their brand of spirituality is genuine and meaningful and other approaches are false and manipulative

I think my own brand is plenty manipulative, and I'm not sure I believe any of them are "false." (Okay, the flat-earthers and the breatharians have some serious "false" going on. But aside from scientifically provable falsehoods, I don't think a religion's tenets are "true" or "false" in any meaningful way.)

(Scripture says: All affirmations are true in some sense, false in some sense, meaningless in some sense, true and false in some sense, true and meaningless in some sense, false and meaningless in some sense, and true and false and meaningless in some sense.)

Timothy Leary said that the purpose of religion was to deal with seven basic spiritual questions, and provide "ecstatic, incontrovertibly certain, subjective discovery of answers" to those questions. I'm still mulling over his definitions.
