In SGI's writings, the character Mu has been dropped ten billion times. Nichiren, on the other hand, never once in forty years ever dropped the character Mu.
"In the ninth volume of the Nirvana Sutra we read: “Good man, there are icchantikas, or persons of incorrigible disbelief. They pretend to be arhats, living in deserted places and speaking slanderously of the correct and equal sutras of the great vehicle. When ordinary people see them, they all suppose that they are true arhats and speak of them as great bodhisattvas.” It also says: “At that time, this sutra will be widely propagated throughout Jambudvīpa. In that age there will be evil monks who will steal this sutra and divide it into many parts, losing the color, scent, and flavor of the correct teaching that it contains. These evil men will read and recite this sutra, but they will ignore and put aside the profound and vital principles that the Thus Come One has expounded in it and replace them with ornate rhetoric and meaningless talk. They will tear off the first part of the sutra and stick it on at the end, tear off the end and put it at the beginning, put the end and the beginning in the middle and the middle at the beginning or the end. You must understand that these evil monks are the companions of the devil."
"Again, a single character equals innumerable others, for the validity of the sutra was attested to by the Buddhas of the ten directions. The treasures bestowed by a single wish-granting jewel equal those bestowed by two such jewels or by innumerable jewels. Likewise, each character in the Lotus Sutra is like a single wish-granting jewel, and the innumerable characters of the sutra are like innumerable jewels. The character myō was uttered by two tongues: the tongues of Shakyamuni and Many Treasures. The tongues of these two Buddhas are like an eight-petaled lotus flower, one petal overlapping another, on which rests a jewel, the character of myō.
"A single character of the Lotus Sutra is like the great earth, which gives rise to all things. A single character is like the great ocean, which contains the water from all rivers. A single character is like the sun and moon, which illuminate all four continents.
"Similarly, though we gather together all the various sutras, such as the Flower Garland Sutra, the Āgama sutras, the Correct and Equal sutras, the Wisdom, Nirvana, Mahāvairochana, and Meditation sutras, they could never equal even a single character of the Lotus Sutra."
"...Every single character in this sutra represents the true intention of the Buddhas, and every brushstroke of it is a source of aid to those who repeat the cycle of birth and death. There is not a single word in it that is untrue."
“The Lotus Sutra of the Wonderful Law, before which I bow my head, in its single case, with its eight scrolls, twenty-eight chapters, and 69,384 characters, is in each and every one of its characters the true Buddha who preaches the Law for the benefit of living beings.”
"Every single character in this sutra represents the true intention of the Buddhas, and every brushstroke of it is a source of aid to those who repeat the cycle of birth and death. There is not a single word in it that is untrue."
"If one discards one word or even one brushstroke of the sutra, the offense is graver than that of one who kills one’s parents ten million times over, or even of one who sheds the blood of all the Buddhas in the ten directions."
"The eighth volume of The Annotations on “Great Concentration and Insight” states, “So long as a person does not try to depart from the sufferings of birth and death and aspire to the Buddha vehicle, the devilwill watch over him like a parent.” This passage means that, even thougha person may cultivate roots of goodness, so long as he practicesNembutsu, True Word, Zen, Precepts, or any teaching other than theLotus Sutra, he will have the devil king for a parent. The devil king will possess and cause other persons to respect him and give him alms, and people will be deluded into believing that he is a truly enlightened priest. If he is honored by the sovereign, for instance, the people are sureto offer him alms. On the other hand, a priest who incurs the enmity of the ruler and others [because of the Lotus Sutra] is surely practicing the correct teaching."
For this reason alone, SGI is not Nichiren's Lotus Sutra Buddhism. For this reason alone, not one Gakkai member receives the boundless benefit of the Law.
