So I was doing some research just into general info for my WIP. It seems that Buddha had a lot of pertinent teachings that would apply to many of the events in my book. Could I use direct lines from his teachings? Or from others, Socrates. (HAHA So-Crates, I need to watch that movie again), Confucius, even Martin Luther King Jr? (not ancient I know). Or would I need to reword it and try to make it my own?
