It never sat right with me that Yoda would want the old ways of the Jedi 2 continue. Wasn’t part of the PT & OT all about Yoda learning the old ways were flawed & problematic ?
Yoda already knew the books were elsewhere. That conversation was about having Luke let go of the shame and fear that paralysed him. Yoda wasn’t saying the Jedi needed to end, he was teaching his student to let go and trust again.
