[W]hen Hinayāna people are shackled by Hinayāna teachings and go against Mahāyāna principles or try to be equal to Mahāyāna countries although they do not intend to go against Mahāyāna Buddhism, they (Hinayāna Buddhists) and their countries will contract various sicknesses. When they try to cure their mental sickness by means of the teaching of Hinayāna Buddhism, they only intensify their troubles instead of curing them. Only practicers of Mahāyāna sūtras can cure them.

Likewise, when believers of provisional Mahāyāna sūtras … adhere to their biased opinions, insisting that their inferior faith equals or is even superior to the Lotus Sūtra, and when rulers of the land recognize them without discerning their prejudices, the 84,000 mental sicknesses such as the three poisons will be begotten. The harder they try to heal the sickness by means of their respective canonical sūtras, the worse their troubles will be. Even if they try to cure their troubles by the Lotus Sūtra, it will not work. It is not because the sūtra is not good enough but because the people who try to use it are prejudiced.
