Chapter 25 of the Lotus Sutra lists seven disasters from which one can be saved by the power of Bodhisattva Perceiver of the World’s Sounds: (1) fire, (2) flood, (3) rākshasa demons, (4) attack by swords and staves, (5) attack by yaksha and other demons, (6) imprisonment, and (7) attack by bandits.
2. Reference is to Ryōkan, chief priest of Gokuraku-ji temple. In a play on words, the Daishonin changes the name Ryōkan-bō (Priest Ryōkan) to Ryōka-bō, which means Priest Two Fires.
3. T’ien-t’ai’s doctrine that all of the three thousand realms theoretically exist in all beings.
