My apologies for any ignorance of the teachings of Nichiren Daishonin and I again apologize if this is the wrong part of the forum to post in but I fear if I were to post this in the Nichiren Buddhism section not too many would read my post but this is the part of the forum where interpretations are argued so I think I am alright. I don't want to overpost so I'll wait for a few weeks before I post again
According to Nichiren the Lotus Sutra is the highest teaching of the Buddha and all previous sutras were provisional and were used to prepare for the Lotus Sutra and thus only the Lotus Sutra contains what is needed for a disciple's salvation.
In his letter 'Questions and Answers About Embracing The Lotus Sutra' (Which can be found at this link http://www.sgilibrary.org/view.php?page=55&m=0&q= ) he states:
If you think that to proclaim the absolute superiority of the Lotus Sutra is to take too narrow a view, then one would have to conclude that no one in the world was more narrow-minded than Shakyamuni Buddha. I am afraid you are greatly mistaken in this matter. Let me quote from one of the sutras and from the commentary of one school, and see if I can resolve your confusion.
The Immeasurable Meanings Sutra says: “[Because people’s natures and desires are not alike], I preached the Law in various different ways. Preaching the Law in various different ways, I made use of the power of expedient means. But in these more than forty years, I have not yet revealed the truth.”
Hearing this pronouncement, Great Adornment and the others of the eighty thousand bodhisattvas replied in unison, voicing their understanding that “[as for those living beings who are unable to hear this sutra . . . ] though immeasurable, boundless, inconceivable asamkhya kalpas may pass, they will in the end fail to gain unsurpassed enlightenment.”
The point of this passage is to make clear that, no matter how much one may aspire to the Buddha way by calling upon the name of Amida Buddha, or by embracing the teachings of the Zen school—relying on the sutras of the Flower Garland, Agama, Correct and Equal, and Wisdom periods preached by the Buddha during the previous forty years and more—one will never succeed in attaining supreme enlightenment, even though a countless, limitless, inconceivable number of asamkhya kalpas should pass.
And this is not the only passage of this type. The “Expedient Means” chapter of the Lotus Sutra states, “The World-Honored One has long expounded his doctrines and now must reveal the truth.” It also says, “[In the Buddha lands of the ten directions] there is only the Law of the one vehicle, there are not two, there are not three.” These passages mean that only this [Lotus] sutra represents the truth.
