It is said in the Lotus Sūtra, fascicle 5 (chapter 14): “This Lotus Sūtra is the secret treasure of all Buddhas. It is supreme of all sūtras.” Please note that “it is supreme of all sūtras.” According to this sūtra, therefore, he who insists that the Lotus Sūtra is supreme of all sūtras is a true practicer of the Lotus Sūtra, isn’t he? Nevertheless, many who are revered in the land insist that there are sūtras superior to the Lotus. Standing against these monks, who are revered by the king and his subjects, the practicer of the Lotus Sūtra is poor and powerless, with all the people in the land despising him. Under such circumstances, if he points out their sin of slandering the True Dharma as stubbornly as Never Despising Bodhisattva or as decisively as Commentator Bhadraruci defeated Brahman, the Boaster, his life will be in jeopardy. This seems of prime importance. This fits me, Nichiren.
