Thus, only those who thoroughly discern the difference between the Lotus Sūtra and other sūtras can truly be said to have understood the teaching.

Many scholars today do not understand this correctly, so very few seem to have truly understood the teaching. As there are few scholars who understand the teaching, there are only few who truly read the Lotus Sūtra. If no one reads the Lotus Sūtra, there will be no one who can lead the country wisely. If there is no right leader, the people of the country will not know the difference between Hinayāna and Mahāyāna, provisional and true teachings, and exoteric and esoteric teachings. As a result, no one will be able to leave the transmigration of birth and death, and everyone will become a slanderer of the Dharma. More people than the number of dust-particles in the earth will believe in evil dharmas and fall into the Hell of Incessant Suffering. Those who leave the delusion of life and death through the right teaching are scarcer than the amount of soil on a fingernail. How terrible this is!
