[S]cholars today, while praising the Lotus Sūtra as superior to all other scriptures, maintain it is unsuitable for the inferior capacity of the people in the Latter Age, a contention that people accept. Are they not the slanderers of the True Dharma? You should wholeheartedly reject these scholars. After all, the text of the Lotus Sūtra can be broken up or cut up, but its spirit cannot be destroyed. Even if someone criticizes the Lotus Sūtra by comparing conducts of evil in the world with the practice of the Lotus Sūtra, people will not believe him. Only when someone slanders the Lotus Sūtra with the provisional doctrine similar to that of the Lotus Sūtra, will people be deceived.
