[L]et me explain why we should discard provisional sūtras, putting faith in the true sūtras instead.

QUESTION: What scriptural statements support your contention?

ANSWER: Ten scriptural statements support my contention. First, it is stated in the Lotus Sūtra, chapter 3 on the “Parable,” “You should try to uphold only Mahāyāna sūtras … without putting faith in even a verse of other sūtras.”

Secondly, the Nirvana Sūtra states, “We should depend on sūtras which thoroughly reveal the truth and not on those which do not.” Sūtras which do not thoroughly reveal the truth refer to those sūtras expounded in forty years or so before the Lotus Sūtra.

Thirdly, it is stated in the Lotus Sūtra, chapter 11 on the “Appearance of the Stupa of Treasures”, “It is difficult to uphold this sūtra. If anyone upholds it even for a moment, I, as well as the other Buddhas, will rejoice and praise him. He is a man of valor and endeavor; he is observing the precepts and practicing the rules of frugal living.” In the Latter Age of Degeneration, we may not observe various precepts defined in the sūtras expounded during forty years or so before the Lotus Sūtra. Upholding the Lotus Sūtra single-mindedly may be called observing the precepts and rules of frugal living.

Fourthly, the Nirvana Sūtra states, “Those who do not exhort themselves to uphold the dharma may be called indolent, but those who do not exhort themselves to observe the precepts may not be. Bodhisattvas, if you are not lax in putting faith in this Mahāyāna dharma, you deserve to be called the upholders of the precepts. In order to uphold that True Dharma, you bathe in the water of Mahāyāna. Therefore, even when bodhisattvas break the precepts, they may not be called indolent.” This scriptural passage elaborates the spirit of observing the precepts in the Lotus Sūtra.

For the fifth, it is stated in the Lotus Sūtra, fascicle 4, chapter 11 on the “Appearance of the Stupa of Treasures”, “The Lotus Sūtra is entirely true.” This is the attestation by the Buddha of Many Treasures.

For the sixth, in the Lotus Sūtra, fascicle 8, chapter 28 on the “Encouragement of Universal Sage Bodhisattva, Universal Sage Bodhisattva, swearing to Śākyamuni Buddha, declares, “I will make sure that this sūtra will be spread all over the world (Jambudvīpa) and not be destroyed after the extinction of the Buddha.”

For the seventh, it is stated in the Lotus Sūtra, fascicle 7, chapter 23 on the “Previous Life of Medicine King Bodhisattva”, “I will not let this sūtra perish in the world (Jambudvīpa) during the fifth 500-year period after My extinction.” This is an oath by Śākyamuni Buddha Himself.

For the eighth, explaining why the Buddha of Many Treasures and various Buddhas manifested in many worlds all over the universe gathered together around Śākyamuni Buddha, the Lotus Sūtra, fascicle 4, chapter 11, on the “Appearance of the Stupa of Treasures” declares, “They have come together in order to perpetuate the dharma in this world.”

For the ninth, regarding the place where practicers of the Lotus Sūtra reside, the sūtra, fascicle 7, chapter 21 on the “Divine Powers of the Buddha” preaches:

“After the extinction of the Buddha, you should single-mindedly uphold, read, recite, expound, copy this sūtra and act according to its teachings. … Wherever a copy of this sūtra is, regardless where it may be, in a garden, in a forest, under a tree, in a monastery, in the house of a layman, in a hall, in a mountain, in a valley or in a wilderness, a Stupa should be erected and offerings be made to it. Why should it be? It is because this is the place of enlightenment. It was here that Buddhas attained Buddhahood.”

And for the tenth, it is stated in fascicle 9 of the Nirvana Sūtra, a sūtra preached for amplification of the Lotus Sūtra:

“During the last 80 years when the True Dharma will be about to expire after My death, this sūtra will spread widely in this world (Jambudvīpa). Then, however, evil monks will steal this sūtra, cutting it up into pieces to kill its original color, fragrance and flavor. In reading this sūtra, unable to understand the essence of the Buddha’s profound enlightenment, they will insert flowery phrases and meaningless sentences just to save appearances. They might put a beginning sentence at the end, an ending sentence at the beginning, a beginning or ending sentence in the middle, or a middle sentence at the beginning or at the end. You should know that these evil monks are not the Buddha’s disciples but the Devil’s companions. … Those evil monks are like a dairymaid who dilutes cow’s milk with much water to make a quick profit. Likewise, they will mix the Buddha’s words in this sūtra with worldly words, making it misleading. Many people will not be able to talk about, copy and comprehend this sūtra correctly, or be able to praise, make offerings to and revere it. Guided solely by self-interest, those wicked monks will be unable to spread this sūtra widely; it will spread so slightly that it will not be worth mentioning. It is just like a poor dairymaid selling cow’s milk, which was resold and repurchased many times. …When, finally, milk gruel is made of it, it will have no taste of milk. Likewise, this great Nirvana Sūtra, a Mahāyāna sūtra, while being transmitted from person to person, will lose its flavor until in the end it will be tasteless. Nevertheless, it is still 1,000 times superior to other sūtras just as the taste of milk, no matter how much diluted, is 1,000 times better than the taste of bitterness. It is because this great Nirvana Sūtra, a Mahāyāna sūtra, is supreme of all the sūtras transmitted by the direct disciples of Śākyamuni Buddha.”
