According to this legend, Masakado conquered eight provinces with the gorisho (prayer answered) of Myoken Bosatsu, but because he had a cruel heart, paid no mind to what the gods might think, and had no fear of the Emperor's authority, Myoken Bosatsu crossed over to TAIRA no Yoshifumi's side, who was Masakado's uncle (an older brother of Masakado's father through adaption who was in actuality, younger brother of Masakado's father).
この伝説によると将門は、妙見菩薩の御利生で八カ国を打ち随えたが、凶悪の心をかまえ神慮に憚らず帝威にも恐れなかったため、妙見菩薩は将門の伯父にして養子（実際には叔父）の平良文の元に渡ったとされる。
