Nichiju's disciples are all equal. Nichiju's last will and testament.

"Among the disciples of the school of Nichiju, nobody should be chosen, directly or indirectly as an heir disciple. However, anybody among the priests or the laymen of my congregation that spreads the teaching in Kyoto and swears that other sects are the root of all evils and that only the Hokke Sect makes us enter Nirvana can be my disciple. And if candidates are equally gifted, they should propagate during the summer, practicing in turn. You should consider a person who spreads the teaching like this as the true disciple of Nichiju and Nichiren Shonin. So in the days to come, this shall be my will."
