[We learn in Chapter 10, The Teacher of the Dharma, that] if a teacher of the Dharma expounds the Sutra here in this evil world, where the Dharma will be little appreciated after the Buddha’s extinction, he might well be persecuted with swords, sticks, tile-pieces, or stones. However, Sakyamuni will create laymen and monks by his supernatural powers, and send them to protect him, although the Buddha himself will not appear.
The teacher of the Dharma will be protected because he is inspired by the power of the Buddha, and his renewed strength can be seen as a manifestation of the Buddha himself. In this respect, the Sutra says, “He (the teacher of the Dharma) will be covered by my robe;” he will be “borne on the Buddha’s shoulders,” or “reside with the Buddha, who will pat him on his head.”
