Bodhisattvas are to choose words carefully and make no mistakes in expounding the Dharma. There are four points:

1. A Bodhisattva should not point out the faults of other sutras or their adherents.
2. He or she should not despise other preachers of the Dharma.
3. He or she should not speak of either the merits or the demerits of other preachers, and should not mention “hearers” by name when criticizing their teachings or even when prais ing them.
4. He or she should not feel hostile toward anybody, and should freely answer any questions put to him. When asked difficult questions, the Bodhisattva should not answer by the teachings of the Lesser Vehicle, but always refer to the Great Vehicle, and so lead people to the “knowledge of the equality and differences of all things” (p. 216).
