Acharya Prashant addresses the distinction between speaking with depth and merely projecting confidence through gibberish. He explains that the problem is not fluency or confidence itself, but the tendency to prioritize the exterior style over the internal substance. He emphasizes that the center from which words originate is what truly matters. If one's eloquence arises from deep clarity, it is valid; however, if the center is wrong, even the most polished and impressive personality remains toxic. He advises that substance should decide the style, and one should not be concerned with being impressive or dominating others, but rather with illuminating them for the sake of truth.
