This letter was written at Minobu in the fifth month of the third year of Kōan (1280). The lay nun Myōichi was a relative of Nisshō, one of Nichiren Daishonin’s six senior disciples, and lived in Kamakura. She was an earnest believer and fairly well educated, but suffered from poor health. Her husband was also a believer, and their fief was confiscated because of their faith. After her husband died, the lay nun was left with two small children, but despite her many difficulties, she remained loyal to the Daishonin.
