Nichiren’s criticism of other sects has formed a significant part of his teaching and writing. Among his works, thirty-eight are criticisms, and in [Chigaku] Tanaka’s edition of Collected Works they constitute a special part, the Taihon hen or “Part of Polemical Classification.” His criticism began with the establishment of his sect, and though there are other works that are as equally representative, the Kenhōbō-shō or “The Treatise on the Manifestation of Slandering the Teaching” probably gives his argument in the most general and comprehensible way. He argues: Breaking the Mahāyāna sūtras from the standpoint of Hinayāna sūtras means blaspheming the right teaching and is a sin, but breaking the Hinayāna sūtras from the standpoint of the Mahāyāna sūtras is no blasphemy and no sin. Breaking the Hoke-kyō from the standpoint of General Mahāyāna means blaspheming the right teaching and is a sin; but breaking the various Mahāyāna sūtras from the standpoint of the Hoke-kyō is not a blasphemy or a sin. This argument forms the basis of Nichiren’s embittered fight against other sects.
