Acharya Prashant explains that the purpose of communication is not merely to transmit ideas but to ensure that the listener receives and understands them correctly. The speaker is responsible for how their words are interpreted and construed. If a speaker finds that their audience reacts with resistance or provocation, their purpose is not being served. He warns that the ego can find pleasure in instigating others to feel powerful, but true communication requires empathy. A speaker must consider the listener's state of mind, biases, and pains, choosing the right language, tone, and timing to facilitate genuine listening.
