Nichiren explains, "in this life or the next."

Ordinary peoples' tongues burn when exposed to fire and others' may become cancerous. Leprosy and bullous disease is associated with slander of the Law. Reality is as it is. It is cause and effect and the teachings of Buddhism. It is very hard to realize that one is a slanderer of the Law. It is difficult to believe that one has met and practices a counterfeit Law because of one's own past slanders. The Nichiren Shoshu and Soka Gakkai teachings are the counterfeit Law for the Latter Day since it is based on a counterfeit Object of Worship and counterfeit teachings. Nichiu forged the Nichiren Shoshu Object of Worship and became a leper. NST and SGI members are no longer innocent or unaware of the reality. Therefore, they are complicit. If they do not repudiate the Nichiren Shoshu, the DaiGohonzon, and the Soka Gakkai teachings, they will suffer a similar fate to Nichiu in this life or the next.

Nichiren explains in Letter to Horen:

"Question: Your argument is that, though you are a votary of the Lotus Sutra, your advice is not heeded, and therefore these heavenly calamities and strange occurrences on earth arise. But the eighth volume of the Lotus Sutra states, “Their heads will split into seven pieces.”41 And the fifth volume states, “If people speak ill of and revile him, their mouths will be closed and stopped up.” Why is it that though you have been cursed and treated with animosity for many years now these latter things have not occurred?

Answer: By way of answer, let me ask in turn if the people who cursed and reviled and beat Bodhisattva Never Disparaging had their mouths stopped or their heads split apart?

Question: [They did not.] But in that case, the text of the sutra is not consistent with itself, is it?

Answer: There are two types of people who show animosity toward the Lotus Sutra. The first are people who cultivated the roots of goodness in former existences, who in their present existence are searching for some connection with Buddhism, who conceive a desire for enlightenment and are capable of attaining Buddhahood. It is these people whose mouths are stopped or whose heads split apart.

The other type are people who have slandered the correct teaching in their previous existences, slander it in their present existence, and for existence after existence go on creating karma that will condemn them to the hell of incessant suffering. These people, even though they may curse, will not have their mouths stopped. They are like men who have already been sentenced to execution and are awaiting their turn in prison. While they are in prison, regardless of what evil acts they may commit, they will receive no further punishment other than the death sentence already passed upon them. However, with regard to people who are eventually to be released, if they commit evil acts in prison, then they will receive warnings.

Question: Since this is a very important point, may I ask you to explain it in detail?

Answer: It is explained in the Nirvana Sutra and in the Lotus Sutra.
