I want to know the answer to the following question:
Buddhism may have spread quickly because of what Mauryan emperor?
All the background I'm provided with is that "These two missions, in opposite directions, would ultimately lead, in the first case to the spread of Buddhism into China, and in the second case, to the emergence of Theravāda Buddhism and its spread from Sri Lanka to the coastal lands of Southeast Asia.". Is that enough to answer the question?
