QUESTION: How should we comprehend the statement in the chapter 3, “A Parable,” of the Lotus Sūtra, “You should not expound this sūtra to ignorant people”?
ANSWER: This applies to wise masters, who are able to discern the capacity of people, not to ordinary masters in the Latter Age of Degeneration.
We should also solely expound the Lotus Sūtra to those who slander the Dharma. This would establish the connection of a poisonous drum between the unfaithful people and the Lotus Sūtra as it is said that the sound of a drum smeared with poison kills a man who hears them. It is like the practice of Never-Despising Bodhisattva preached in the “Never-Despising Bodhisattva” chapter of the Lotus Sūtra.
If a person has the capacity of a wise man, though, we should teach him the Hinayāna sūtras first of all, then the provisional Mahāyāna sūtras, and finally the true Mahāyāna sūtra, the Lotus Sūtra. If a man is deemed ignorant, however, we should teach him the true Mahāyāna sūtra from the start, as it can plant the seed of Buddhahood in both believers and slanderers.
