Nichiren states that any of the teachings of the Buddha’s fifty years of teaching are a great vehicle of salvation compared to the non-Buddhist teachings. This is because the other teachings either do not teach about karma and rebirth in the six worlds or they do not show how to thoroughly extinguish the greed, hatred, delusion and other defilements that perpetuate the cycle of rebirth. At the same time, there are differences in degrees of profundity even among the Buddha’s teachings between Mahāyāna and Hinayāna, exoteric and esoteric, accommodating and confrontational rhetoric, and between provisional and final statements of truth. Nichiren asserts that the highest truth can only be found in the Lotus Sūtra, and he cites the testimony of Śākyamuni Buddha, Many Treasures Buddha, and the buddhas of the ten direction in the Lotus Sūtra itself as confirmation of this.
