It is said that Miroku Bosatsu appears as Brahman in this corrupt world, obtains enlightenment under the Ryuge-ju tree (竜華樹) after becoming a priest in the same way as Siddhartha, and brings people relief by preaching three times (which is called Ryuge-sankai, the three sermons at Ryuge).
弥勒菩薩はバラモンとして娑婆世界に出世して、シッダールタ同様に出家したのち竜華樹下(りゅうげじゅ)で悟りを得て、三度にわたり説法を行い多くの人々を救うという（これを竜華三会という）。
