A young man once told Mr. Makiguchi that he thought it would be better to hold large-scale lectures rather than discussion meetings. “No, it wouldn’t,” Mr. Makiguchi
replied without hesitation. “Dialogue is the only way to communicate with another about life’s problems. At a lecture, listeners inevitably feel uninvolved. Even the Daishonin’s treatise ‘On Establishing the Correct Teaching for the Peace of the Land’ was written in the form of a dialogue, you know.”
