It is also pointed out that actually Nehangyo rather than Lotus Sutra explains the bussho josho (one of the Buddhist teachings about the status of reaching the Nirvana and its eternity) of sanjo as well as the logical reason of esankiitsu ("Bukkyo fukyo taikei" and so on).
またこれに従って、法華経に対し涅槃経の方が、三乗の同一仏性の常住を説いて会三帰一の理論的根拠を説いているという指摘もなされている（「仏教布教体系」など）。
