OAHSPE, "The Book of Mormon" and "Akasha Chronicle" are not books handed down since ancient times but documents the revelation of God, inspiration or automatism but there is no problem in defining them as koshi koden as described above.
『OAHSPE』『モルモン経』『アカーシャ年代記』は古代から伝来した書物ではなく神の啓示とか、霊感や自動書記などになるものだが、それは古史古伝の定義上問題ないことは上述の通り。
