All I know is that the Jedi order WAS rebuilt, and that it was more lax then the previous one. i.e. I believe the restriction on love and relationships was lifted, or at least partially lifted
Not lax exactly, with little real information about the force, apart from what Luke had learned, they had too be more flexible. The only way to learn was to experiment, which meant that techniques were less polished, and mistakes were made. They had little or no lore, remember Lukes training was unorthadox and incomplete, Yoda didn't train him as he trained other Jedi, and apart from telling him to avoid anger, hate and fear didn't teach him to dampen his emotions or avoid romance.
