Nichiren Daishonin sent this letter from Minobu in the seventh month, 1278, to the lay nun Myōhō, who lived in Okamiya Village in Suruga Province. Very little is known about Myōhō. This letter was written in response to a letter she had sent the Daishonin, asking whether one can attain enlightenment by chanting Nam-myoho-renge-kyo alone. A later letter from the Daishonin to Myōhō tells us that the lay nun’s husband died shortly after the present letter was written, and that her inquiry was most likely made on behalf of her sick husband. She survived her husband and her elder brother. She was a sincere believer and received several letters from the Daishonin, who apparently placed great trust in her. https://www.nichirenlibrary.org/en/wnd-1/Content/121
