Treatise of Five Hundred Questions, The ［五百問論］ (Chin Wu-pai-wen-lun;  Gohyaku-mon-ron): A work by Miao-lo (711–782) in question-and-answer form that refutes Praising the Profundity of the Lotus Sutra by Tz’u-en (632–682), the founder of the Chinese Dharma Characteristics (Fa-hsiang) school. In it, Miao-lo poses a question concerning a given subject, presents as an answer Tz’u-en’s view on the subject from his Praising the Profundity of the Lotus Sutra, and then points out the error of Tz’u-en’s view. Thus Miao-lo concludes that, although Tz’u-en praised the Lotus Sutra, he misunderstood its meaning because he interpreted it from the standpoint of the Dharma Characteristics doctrine. The treatise contains some 371 questions and answers, but because some of these contain questions within them, it actually addresses more than five hundred questions in all.
