Teacher's Discourse was indeed inextricably linked to Lu PingAn.
It was made up of the many ideas and philosophies Lu PingAn had revealed while training the local warriors. It was full of armchair politics and personal opinions, but it had indeed originated from Lu PingAn's own thoughts.
But just like the current state of affairs that even he himself could not recognize, as words were passed along, they changed until even their original speaker could no longer recognize them.
"Too many people added their own ingredients during the process of spreading it."
The disciples trained back then all had their own understandings and ideas. They accepted Lu PingAn's thoughts, but also added content of their own.
It was only natural that Lu PingAn could not recognize it, because not only had it been mixed with far too much random nonsense, it was also the result of many "apprentices" thinking, discussing, and localizing it.
For example, Lu PingAn had once talked at length about class and mentioned certain concepts of social development.
"It really wasn't as stirring as casually saying, 'All men are born equal.'"
Things Lu Mouren had long grown sick of seeing were deeply stirring in a world where people were clearly not born equal—especially now, when outer-domain races could use Longhands and Free Fishmen as slaves, food, or toys. This "equality" alone was enough to inflame people's hearts.
Lu PingAn had said a great deal. Even he did not know which of his words were the key points, or which ones could truly move the locals. But his apprentices naturally treated them as key headings in Teacher's Discourse and added their own interpretations.
"The reason Teacher's Discourse is so popular is ultimately because there is simply too much suffering in this world..."
