Acharya Prashant explains that communication between a knower and their audience is inherently difficult because the essence of truth cannot be captured in words. The knower understands the futility of verbal skills and uses language sparingly, as seen in the pithy verses of the Upanishads and the sparse language of Lalla. Furthermore, listeners often distort the message by assigning pre-existing mental images to words, preventing the communication of anything truly new. He emphasizes that any peace or calmness experienced in the presence of a teacher is not caused by their words but is a prior state; attributing it to words is a mental error that leads to the peace disappearing once the speaking stops.
