For example, Esoteric Buddhism-related books, such as "Story of Mt. Koya," explain that the Ama-no-iwato myth (Shinto goddess of the Sun hid behind the Cave of Heaven but was enticed out by many deities) depicts the following process: the gate of the iron pagoda in Nantenjiku (South India) opens thanks to the merciful glow of Vairocana Buddha (metaphor of achieving enlightenment) when the enlightenment of all creatures was covered by the long night of earthly desires.
例えば、『高野物語』など密教関連の書物では、天岩戸神話を、衆生本覚の悟りを煩悩の「長夜」が覆い隠していたところを、大日如来の光明により南天竺の鉄塔が開く（仏性を得る寓意）様を著したものと解釈する。
