Under such circumstances, the religious order tried to survive by organizing an underground organization consisting of hocchu (Buddhist priest), horyu (法立, believers of fujufuse) and naishin (内信, believers who ostensibly pretended to believe in other sects or schools).
このような状況において教団は、法中（僧侶）-法立（不受不施信者）-内信（外見上他宗他派を装う信者）という地下組織化の道をとり、教団の存続を図った。
