I want to know the answer to the following question:
What were the emissaries used for?
All the background I'm provided with is that "According to the edicts of Aśoka, emissaries were sent to various countries west of India to spread Buddhism (Dharma), particularly in eastern provinces of the neighboring Seleucid Empire, and even farther to Hellenistic kingdoms of the Mediterranean.". Is that enough to answer the question?
