"Nothing True is Popular and nothing Popular is True".

So many examples. Tucker Carlson, Laura Ingraham, Sean Hannity on Fox cable "news" are very popular but almost completely false. Same for Glen Beck and Hannity on the radio. Donald Trump is rabidly popular but nearly everything that comes out of his moth is toxic and false.

Regarding Soka Gakkai Buddhism certainly this is true. It is popular and untrue while the authentic and true Lotus Sutra Buddhism of Nichiren is unpopular. Nichiren foresaw this studying the Nirvana Sutra:

And the Nirvana Sutra says, “Those who thus are able to take faith in works such as this Nirvana Sutra will be as few as the specks of dirt that can be placed on a fingernail.... But those who are not able to take faith in this sutra will be as numerous as the specks of dirt in all the worlds of the ten directions.”

These passages from the scriptures are extremely apt, considering the times we live in, and they are deeply etched in my mind. Nowadays in Japan one hears people everywhere declaring, “I believe in the Lotus Sutra,” and “I, too, believe in the Lotus Sutra.” If we took them at their word, we would have to conclude that there is not a soul who slanders the Law. But the passage from the sutra that I have just quoted says that in the Latter Day the slanderers of the Law will occupy all the lands in the ten directions, while those who uphold the correct teaching will take up no more land than can be placed on top of a fingernail. What the sutra says and what the people of the world today say are as different as fire is from water. People these days say that, in Japan, Nichiren is the only one who slanders the Law. But the sutra says that there will be more slanderers of the Law than the great earth itself can hold.

The Decline of the Law Sutra says that there will be only one or two good persons, and the Nirvana Sutra says that the believers can fit into the space of a fingernail. If we accept what the sutras say, then in Japan Nichiren is the only good person, the one who fits into the space of a fingernail. Therefore, I hope that people who are seriously concerned about the matter will consider carefully whether they want to accept what the sutras say, or what the world says.

Someone might object that the passage in the Nirvana Sutra speaks about the votaries of the Nirvana Sutra being as few as the specks of dirt that can be placed on a fingernail, while I am talking about the Lotus Sutra. I would reply to this as follows.

The Nirvana Sutra itself says, “[When this sutra was preached . . . the prediction had already been made] in the Lotus Sutra [that the eight thousand voice-hearers would attain Buddhahood].” The Great Teacher Miao-lo says, “The Nirvana Sutra is itself pointing to the Lotus Sutra and saying that it is the ultimate.”77 The Nirvana Sutra is calling the Lotus Sutra the ultimate. Therefore, when followers of the Nirvana school state that the Nirvana Sutra is superior to the Lotus Sutra, it is the same as calling a retainer a lord or a servant a master.

To read the Nirvana Sutra means to read the Lotus Sutra. For the Nirvana Sutra is like a worthy who rejoices to see another holding his sovereign in esteem even when he himself is treated with contempt. Thus the Nirvana Sutra would despise and regard as its enemy anyone who tried to demote the Lotus Sutra and praise the Nirvana Sutra instead." - On Repaying Debts of Gratitude, One of Nichiren's Five Major Works
