Concerning the judgment of the comparative superiority of the Buddhist sūtras in the future, the Buddha preached in the Nirvana Sūtra, “Rely upon reason, not upon men.” Bodhisattva Nāgārjuna stated in his Commentary on the Ten Stages, “It is right to depend on the sūtra; it is not right not to depend on the sūtra.” T’ien-t’ai said in the Profound Meaning of the Lotus Sūtra, “Accept what is in accordance with the sūtra; not to believe in what is not said in the sūtra in letter or in spirit.” Grand Master Dengyō in his Outstanding Principles of the Lotus Sūtra said, “Rely upon what the Buddha preached; never believe in what is transmitted orally.”
