It is the fault of deceitful priests and leaders, weak willed, unlearned disciples, and those with poor karmic roots, not the Buddha and Nichiren

"If the Lotus Sutra and the Gosho were adequate by themselves and we didn't need some sort of mentoring there wouldn't be hundreds of Nichiren Sects as one could simply pick up the Gosho and all the doctrines necessary would be there." -- SGI member

There are "hundreds" [36 actually] of Nichiren sects. It is precisely because they follow the person rather than the one Law that there are so many Nichiren sects. Many claim to follow the Lotus Sutra and Gosho, stating, "We rely on the Lotus Sutra and the Gosho", when nothing could be further from the truth. Even among those who do sincerely attempt to follow the Lotus Sutra and Gosho, many get lost in the thickets of faulty translations and an inability to act as one speaks. Nichiren Daishonin teaches, "If a man builds a road for others and someone loses his way on it, is that the fault of the road-builder? If a skilled physician gives medicine to a sick person but the sick person, repelled by the medicine, refuses to take it and dies, should one blame the physician?". You are placing the blame on the Buddha and Nichiren Daishonin when the blame lies squarely with the deceitful priests and leaders and the weak-willed and unlearned disciples. It is also due to poor karmic roots. Failing to place the blame squarely on themselves, they place the blame on the Buddha [Lotus Sutra] and Nichiren Daishonin.
