also recorded sayings, language, a "cannon" of sages e.g. wise ancestors, high holidays, celebratory events, rites of passage, information on how to cultivate the mind and the land... it's not enough to just make a book, you can put basic information in a book (and encode it to guard it against those who would abuse it) but you need people to relay the understandings. so then you get to tradition, and religions are wisdom traditions. ethno-religions are the most primitive form of that but you cannot skip this step.
