The Stories of the Lotus Sutra, p125-126The most important thing about [Chapter 10] is its emphasis on the Dharma teacher. Here we can see that the Sutra attempts to break through the limitations of the threefold shravaka-pratyekabuddha-bodhisattva distinction that had been prominent in earlier chapters of this Sutra and elsewhere in Mahayana Buddhism. According to Chapter 10, anyone – bodhisattva, pratyekabuddha, shravaka, or layperson, man or woman – can be a Dharma teacher.
This important point is certainly not unique to this chapter, but it is emphasized here in a special way: it is not only great bodhisattvas, great leaders, or great people who can teach the Dharma and do the Buddha’s work, but very ordinary people with even a limited understanding and even of limited faith can join in the Buddha’s work, if only by understanding and teaching a little. The point is, of course, that you and I can be Dharma teachers.
Thus the Buddha tells Medicine King Bodhisattva that if anyone wants to know what sort of living beings will become buddhas in the future, he should tell them that the very people before him, that is, all sorts of people, including very ordinary people, will become buddhas.
