The late Shichirō Gorō is different from these people in Japan today. He obeyed his father from childhood and chanted “Namu Myōhō Renge Kyō” before the age of twenty. I am sure he must have attained Buddhahood because it is stated in the Lotus Sūtra: “All those who listen to the Lotus Sūtra will never fail to become a Buddha.” If you really love your son, you should chant “Namu Myōhō Renge Kyō” and pray so that you, your husband, the late Lord Nanjō, and your son, the late Gorō, will be reborn in the same place. One seed will be the same one-seed all the way; a different seed will be a different seed all the way. If you plant the same seed of the Lotus Sūtra in your heart, you will be reborn in the same land of the Lotus Sūtra as your husband and son. When you three meet again face to face, how happy you will be!
