It is I, Nichiren, who is the richest in Japan today, because I sacrifice my life for the sake of the Lotus Sūtra and leave my name for posterity. Gods of rivers take orders from the master of a great ocean, and gods of mountains follow the king of Mt. Sumeru. Likewise, when one knows the meaning of the “six difficulties and nine easier actions” and “scriptures preached in the past, are preached at present, and will be preached in the future” in the Lotus Sūtra, one will automatically know the comparative merits of all the Buddhist scriptures without reading them.
