|This study was focused on the teaching aspects of Buddha. The Buddha is an educator who has led the conversation education that is the best of humanity. I made the appearance of Buddha as an educator even more by using ‘Buddha’s Dialogue’. Buddha’s Dialogue is Buddha’s mind itself. As Buddha attained full enlightenment, he gave his disciples lessons considering each one’s capability and circumstances so that they can also reach perfect enlightenment. Buddha’s Dialogue is not simple technical skill but practical dialogue. Dhamma(法) don’t just mean methods that is a modern conception of the ideas. It is not good to divide Buddha’s Dialogue into its contents and methods or contents and forms. These characteristics are revealed better through the process of dialogue with the person who be taught by other masters. Buddha practiced the question and answer. Through this, Buddha was a teacher who taught, made to understand, made to have faith, and ultimately to practice. Buddha’s Dialogue teaches everyone a rational attitude to engage in conversation. The question and answer method features : First, Buddha reveals that any argument made by the other party has a logical premise. Second, in the question and answer process, Buddha uses questions so that he or she can realize that the other person has the wrong opinion. Third, the enlightenment of Buddha in the question and answer process becomes an example of those who want to teach.
