Buddhism for Today, p389This chapter declares how with mystic syllables nonhuman beings representing the spiritual world, who are deeply moved by the teachings of the Lotus Sutra, vow to protect the teachings and their preachers.
First two bodhisattvas, Medicine King and Courageous Giver, vow to guard and protect the preachers of the Lotus Sutra. Their vows are only to be expected, for these two bodhisattvas are the disciples and messengers of the Buddha. Next two Brahma heavenly kings, the Divine King Vaiśravaṇa and the Divine King Domain Holder, vow to protect the sutra. The vows of these two non-Buddhist divine kings signify that the Buddha’s teachings comprehend all other teachings and infuse religious life into them.
Following this, ten female rākṣasas and the Mother of Demon Sons vow to protect the Lotus Sutra. These female demons with one voice declared before the Buddha that if anyone harassed the preachers of the sutra, they would protect the preachers and rid them of such persecution. Their declaration bears witness to the fact that the Buddha-mind is found even in these demons. Conversely, the teachings of the Lotus Sutra can be said to have the power to enable even these demons to become buddhas.
