From the film, Luke can already see Master Yoda's soul, then his own soul in vitro, and finally disappear into the sunset. Luke has a deep understanding of the nature of the Force, and naturally he can skim over dogmatic Jedi classics. Simply according to the meaning of China people, he is open-minded.
