So.much of the current Aes Sedai "teachings" come down to misinformation. They sort of took a science (channelling in the Age of Legends) and turned it into a religion. There were some other books I read where a group believed they had to basically "pray a certain way" in order to get their machines to work. The show depicts this in the way the weaves look. If you look at Ishy, Lanfear, and to a greater extent any of the other Age of Legends AS, you see their weaves are precise and structured. Current channellers weaves are clumsy in comparison.
