The painted image of Mitsuhide that remained in the Hontoku-ji Temple in Osaka, which temple looks after Buddhist memorial tablet of Mitsuhide, has a comment that reads '放下般舟三昧去' on its back and, literally, this comment means that Mitsuhide spent his remaining years in Buddhist priesthood.
光秀の位牌を祀る大阪の本徳寺に残存する光秀の肖像画には「放下般舟三昧去」という裏書があり、そのまま読めば光秀は仏門で余生を送ったという意味である。
