One night, when the day of his return was coming up, the empress dowager said that the mysterious lady was her other self and disclosed the secret that "Ubunkai was Asura, I am tenshu (a god) of dainiten (the second god) and you are a tendo (the embodiment as a child of a ferocious god who protects the Buddhist Law) and both were sent from the svarga to punish Asura but obscene thoughts occurred because we are born into this world" and gave him a mirror as a memento.
帰国の日も近づいた或る夜、母后は、あの女性は実は自分の化身だったと言い、宇文会は阿修羅、私は第二天の天衆、あなたは天童、二人は阿修羅懲戒のため天から下されたのだ、人世に生まれたばっかりにみだりごころも起こったのだと秘密を明かし、形見に鏡を渡した。
