Insulting us even jokingly

However, it is said that if one neither at heart thinks ill of the votary of the Lotus Sutra in the latter age nor in one’s bearing shows envy toward him, but merely reviles him in a joking manner, then the consequences will be even worse than those brought about by Devadatta when, by committing the three types of deeds, he cursed and reviled the Buddha for an entire medium kalpa. How much worse, then, would the consequences be if the people of the present age were to set about conducting themselves like Devadatta, carrying out these three types of deeds with truly evil hearts over a period of many years—cursing and reviling the votary of the Lotus Sutra, subjecting him to defamation and insult, envying and feeling jealous of him, beating and striking him, putting him to death under false charges and murdering him." - Letter to Horen
