There used to be countless Buddha names, and then there were 20 thousand Buddha statues with the same name. At the end of the month, before the Buddha became a monk, the Eight Princes learned that his father had become a monk and all gave up the throne and became a monk. They studied Buddhism with Manjusri Bodhisattva before, and later they all became Buddhists again. ("Beijing Wen Sentences" Volume III) P278
