I handed over to you all the doctrines important to my life. I might be a follower of those numerous bodhisattvas who emerged from the earth. This is because I chant “Namu Myōhō Renge Kyō,” trying to lead men and women of Japan to Buddhahood. Is it not stated in the Lotus Sūtra, the “Emerging from the Earth” chapter, “The first was called Superior Practice. … [He was] a guiding teacher”? Because of your strong karmic relationship in past existences, you have become my disciple. Please be very careful dealing with this letter. I wrote the doctrines that I have awakened myself. I will stop writing now.
