When I was exiled to Sado as a prisoner of the Kamakura shogunate, I hardly had any visitors. However, you proved to be an exceptional woman by not only sending many offerings but also personally visiting me over there. I thought that I was dreaming or seeing an illusion when you appeared; and this time you visited me here. I have no words to express my gratitude. I am certain that the gods will protect you and the ten female rākṣasa demons will have compassion on you. The Buddha promised that the Lotus Sūtra would serve woman as a lantern in the darkness, a ship in the sea, and a guardian in dangerous places.
