Not kidding. See for yourselves:

On Gobyo

Looking over the world, you will be surprised to find that there are many cases of Gobyo (sickness as the effect of a man's deeds in his former life) which medicine cannot cure. You will see families unhappy and miserable beyond description, to say nothing of the patient himself. It is excruciating for me to observe them. I feel so sorry for them, and keenly wish I could cure them of their diseases as soon as possible. But alas, I myself am only an average man. How can I know remedies for such diseases, when even doctors fail to cure?

After suffering from acute grife [sic] and sorrow, I know there is no other way than to observe the teachings of Nichiren Daishonin, the True Buddha. When I carefully perused the Gosho (the compete works of Nichiren Daishonin), I found to my surprise that there was clearly given the optimum remedy for any disease or trouble. This is to have faith in the Dai-Gohonzon which is enshrined for all mankind in the high sanctuary of the Taisekiji, the Head Temple of Nichiren Shoshu. Then one must practice faithfully the true Buddhism. When a man has devout faith and practices the teachings diligently, he can appreciate the great power of the Law and the Buddha. There will occur unbelievable events that no mere man can bring about.

Now I would like to give you a more detailed explanation, quoting "A Reply to Lay Priest Ota" (p. 1009 Gosho).

There are six causes for disease.

(1) Irregularity of Shidai (the four elements of earth, water, air and fire). Man suffers from various illness due to a disturbance in any one of the four elements (cold, heat, vitamin deficiency, etc.)

(2) Immoderate eating or drinking (over eating or drinking, malnutrition, or unbalanced diet, etc.).

(3) Lack of uniformity in daily life (excessive or insufficient exercise, lack of sleep, exhaustion, etc.).

(4) A demon taking advantage of one's weakness (germ-carried diseases, such as cholera, dysentery, infant diarrha [sic], etc.).

(5) A demon's behavior becomes the cause of disease (disease of unknown causes).

(6) Go (a man's deeds in his former life) becomes the cause and its effect appears as Gobyo [sickness as the effect of a man's deeds in his former life] in this life.

"Demons". Got it. When is modern medicine going to catch up and develop proper demon-repellent sprays, washes, and ointments? Will we be able to buy them over the counter at the drug store? I wonder if different demons will require different kinds of treatments. Will there be "The No-Demon Diet & Exercise Plan" or that one weird anti-demon trick makes doctors furious? So many questions...

The first three can be treated by physicians, but the others cannot be completely cured. In the case of the fourth and the fifth, there is some hope for recovery. At present, much research is being made on the cures for these two types, and so some extent [sic] the research has been successful. But it is the sixth cause (Go) that even modern medicine can not treat. Especially, Gobyo as a retribution for evil deeds in a former life is the hardest to cure. Polio, psychosis, hydrocephalus, etc., are examples.

Note that modern medicine has virtually eradicated polio, though psychosis remains problematic, especially within the SGI.

Or is there just less Gobyo around? FEWER people slandering the Lotus Sutra now than in previous generations? Or less slandering in nearer generations than more distant generations? How does THIS work?? Is there just less of the specific kind of slander that results in polio? What was that, peeing on the Lotus Sutra? C'mon! Enquiring minds want to know!!

Now I kinda gotta go take a leak...ngl...brb...where's my nohonzon???

What is the cause of Gobyo? ... "The worst sin is slander of the Gohonzon, and illness resulting from this sin is the hardest to cure."

Let's see some EVIDENCE. Oh, wait - we just have to take your word on it? How 'bout that...

It is therefore clear that the hardest of Gobyo to cure is that caused by slander of the Gohonzon committed in a previous life, but slander of the Gohonzon in this life can also be the cause of Gobyo. It can be known from the above-quoted passage.

Because everything this one primitive, superstitious dumbass said 700 years ago MUST be true!!

Slight cases of Gobyo can come from slander of the Gohonzon in this life.

Through these excerpts, it is clear that Gobyo is a retribution for the wrong doings both in the past and present life. Then why can we cure Gobyo by believing in this Gohonzon and practicing the true Buddhism? We know it through the following passage in the above-quoted letter (pp. 1009-10, Gosho):

...The Hokekyo [Lotus Sutra] has great power to cure disease. Therefore it is called Myo (Secret or Wonder)."

Nichiren Daishonin quoted these articles to reveal that the Hokekyo is the best remedy for all disease and that it has mysterious power to turn poison into medicine.

Yet members of the Nichiren religions are NOT healthier than average, regardless of which sect they're members of. Doesn't the Lotus Sutra work any more?? Or is it just a bad idea to repeat stupid primitive superstitious bullshit?? SO much to learn from Nichiren!!

Slander is poison, and the law is good medicine if it can cure disease arising from slander. As the Hokekyo has power to turn the poison of slander (the cause of Gobyo) into good medicine, it is called the law of "Turning poison into medicine'. ...That is to say, it is clear that if a man has sinned in slandering the Hokekyo, there is no other way for him than to have faith in the true Hokekyo.

Hence the idiocy of relying on primitive ignorant nitwits for advice on ANYTHING!

Here, I will offer an example to explain the greatness of the Gohonzon. Suppose there are parents whose child is stricken by polio. Of course, the child cannot worship the Gohonzon. However, the parents can believe in and practice the true Buddhism, [sic] If they worship the Gohonzon with the utmost faith, and practice Shakubuku, their child's disease can be cured completely. But if he is too sinful and therefore there is no hope of recovery, he cannot live any more and will die.

😳

Why must he die? This is the question. The parents with a polio-stricken child have a bad karma that they must have such an unhappy child. Therefore if they efface all the sin through faith in the Gohonzon, they will no more have the helpless fate to have a polio-stricken child. Accordingly, the child will either recover or die.

WTF!!

"It's a GOOD thing your chronically-ill child died! He was just too sinful - his death PROVES it! You should be HAPPY he's dead now! YOU eradicated that bad karma from your life!! It shows you've changed your karma to have such a child! Now you DON'T! Don't you feel FORTUNATE??? CONGRATULATIONS!! Hooray for True Buddhism!! All praise and worship the Gohonzon!!!!"

"Oh, and stop complaining. You should be GLAD your child is dead. You ARE much happier now, AREN'T YOU?? You got a GREAT benefit! You're grateful beyond words, AREN'T YOU?? You don't want to wipe out all your fortune through ingratitude and complaining, do you??"

In addition, I say, the destiny to live homeless or in extreme poverty is also a kind of Gobyo, though it is not a physical one. It is not a joke to say that dire poverty can be cured neither by a skilled physician nor by good medicine. Therefore, people in poverty must also believe in the Dai-Gohonzon and practice Shakubuku assiduously. - Josei Toda, Essays on Buddhism, THE SOKAGAKKAI, 1961 by (THE SEIKYO PRESS), pp. 62-68.

Nice, eh? And SGI members say we're WRONG when we say their preciousssss SGI is full of victim-blaming!

Here's something else from Toda:

"We will cure those cases which the doctors can't. Suppose you have a polio victim. If modern medicine can't make him walk, bring him here. I will cure him." - Toda

I would LOVE to see a devout SGI member declare in plain words that obviously, Toda was at best an uneducated dumbass; his ideas were primitive superstitious twaddle; and he was obviously WRONG, or even that he would pander to people's greatest sufferings and most heartfelt wishes to manipulate and exploit them. But that will NEVER happen. Instead, devout SGI members will insist that Toda never said that (even though it's printed in a book published by the Soka Gakkai) and/or that I am a horrible person & etc., if they are even willing to acknowledge the kinds of stupid things their dear mentor Toda really said.
