One argument was that what he was describing was just very compelling. You no longer have to go through this ruling class, through the priests anymore. You could have your own personal path. It was also perhaps compelling to people who felt marginalized in the traditional hierarchy of the time. Another argument would be the Emperor Ashoka, who we study in other videos, that once he converts to Buddhism after feeling guilty for his war with Kalinga, where tens of thousands, if not hundreds of thousands of people are killed, he converts to Buddhism and becomes a major patron of Buddhism and sends missionaries throughout the world to spread it. So one argument of why Buddhism spread is that a few hundred years after Buddha, you have a significant, powerful emperor converting to the religion and deciding to spread it. Now, that leads us to a second question.
