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. Makiguchireplied 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.”

Daisaku Ikeda

Buddhism doesn’t exist apart from the reality of society or from people and their lives. No matter how valid the teachings of Buddhism may be, just loudly proclaiming that fact will not persuade people. If anything, that approach is quite likely to drive them away from the path of Buddhism, and that would be going against the intent of the Daishonin, who entrusted us with the mission of realizing kosen-rufu.

Daisaku Ikeda

To this day, I am constantly engaged in dialogue with my mentor. In my mind, I stand before him as the youth I was. Kosen-rufu was our shared aspiration, our great dream and adventure as mentor and disciple.
