Nichiren Daishonin states in “The Three Kinds of Treasure”:
It is rare to be born a human being. The number of those endowed with human life is small as the amount of earth one can place on a fingernail. Life as a human being is hard to sustain — as hard as it is for the dew to remain on the grass. But it is better to live a single day with honor than to live to one hundred and twenty and die in disgrace.
宗祖日莲大圣人于《崇峻天皇御书》曰:
人身难受，如爪上之土。人身难持，如草上之露。持寿一百二十，污名而死，不如仅生一日，而扬其名为贵。
Nichiren Daishonin states in “The Daimoku of the Lotus Sutra”:
Amber draws dust and a loadstone attracts iron particles; here our evil karma is like the dust or iron, and the daimoku of the Lotus Sutra is like the amber or the loadstone. If we consider these analogies, we can see why we should always chant Nam-Myoho-Renge-Kyo.
宗祖日莲大圣人于《法华题目抄》曰:
琥珀取尘，磁石吸铁。我等之恶业，如尘如铁，法华经题目，如琥珀，如磁石。须作如是想，常唱南无妙法莲华经。
Nichiren Daishonin states in “The Essence of the Yakuo Chapter”:
The Kegon and the various sutras are like stars in this dark night, while the Lotus Sutra is like the moon in this night. For those who have faith in the Lotus Sutra but whose faith is not deep, it is as though a half moon were illuminating that dark night. But for those who have profound faith, it is as though a full moon were illuminating the night.
宗祖日莲大圣人于《药王品得意抄》曰:
华严经等之一切经，如暗夜之星，法华经如暗夜之月。虽信法华经，然不深信者，如半月之照暗夜。若深信者，如满月之照暗夜。
Nichiren Daishonin states in “Recorded Lectures”:
Now is the time of the Latter Day of the Law, when one can attain Buddhahood by propagating the seven characters of Nam-Myoho-Renge-Kyo, and enable others to receive benefit from the Buddha. Thus, if one mixes the practice of chanting the Daimoku with other practices, it will be a deviation from the correct path. This is the time for one to embrace this great mandala of Myoho-Renge-Kyo, engrave it in one’s heart, and chant the Daimoku aloud.
宗祖日莲大圣人于《御讲闻书》曰:
今末法乃弘通南无妙法莲华经之七字，而有利生得益之时也。故若于此题目混杂余事，则成僻事。当以身持，心念，口唱此妙法之大曼荼罗之时也。
Nichiren Daishonin states in “The True Entity of Life”:
Only I, Nichiren, at first chanted Nam-Myoho-Renge-Kyo, but then two, three and a hundred followers, started chanting and teaching others. Likewise, propagation will unfold, this way in the future. Doesn’t this signify “emerging from the earth?”
宗祖日莲大圣人于《诸法实相抄》曰:
日莲一人首唱南无妙法莲华经，继而二人，三人，百人次第传唱之。未来亦然。此岂非地涌之义乎。
Nichiren Daishonin states in “Teaching, Practising and Proof”:
The five characters of Myoho-Renge-Kyo, the heart of the essential teaching of the Lotus Sutra, contain all the benefits amassed by the beneficial practices and meritorious deeds of all the Buddhas throughout the past, present and future.
宗祖日莲大圣人于《教行证御书》曰:
此法华经本门肝心之妙法莲华经，乃集三世诸佛万行万善之功德为五字。
Nichiren Daishonin states in “How Those Initially Aspiring to the Way Can Attain Buddhahood through the Lotus Sutra”:
One should by all means persist in preaching the Lotus Sutra, thus causing others to hear it. Those who put their faith in it will surely attain Buddhahood, while those who slander it will establish a “poison-drum relationship” with it and will likewise attain Buddhahood.
宗祖日莲大圣人于《法华初心成佛抄》曰:
总之，须强说法华经使其听闻。信者可成佛，谤者成毒鼓之缘，亦可成佛也。
Nichiren Daishonin states in “The True Object of Worship”:
At that time, the bodhisattva of the earth will emerge. Then, he will establish the supreme object of worship of the entire world in this country, with Shakyamuni of the essential teaching playing a subordinate role. This Gohonzon has never before been in existence, either in India or China.
宗祖日莲大圣人于《观心本尊抄》曰:
此时地涌千界出现，以本门释尊为胁士，当于此国，立一阎浮提第一之本尊，月支，震旦未有此本尊。
Nichiren Daishonin states in “Reply to the Wife of Lord Ueno”:
The Lotus Sutra states, “Among those who hear this Law, there is not one who shall not attain enlightenment.” This passage means that if there are a hundred or even a thousand people who embrace this sutra, all will become Buddhas without exception.
宗祖日莲大圣人于《上野尼御前御返事》曰:
经云 “若有闻法者，无一不成佛” 云云。文意乃谓持此经之人，百人则百人，千人则千人，一人不漏皆成佛之文也。
Nichiren Daishonin states in “Opening of the Eyes”:
Although I, Nichiren, and my disciples may face various difficulties, we will attain Buddhahood as a matter of course, as long as we do not harbor doubts [about the teaching of the Lotus Sutra]. Do not doubt that the heavens will protect you. Do not be discouraged because you do not enjoy an easy and secure existence in this life. Though I have taught this to my disciples day and night, many of them, raising doubts, abandon their faith [in the Lotus Sutra]. Those with weak faith always forget what they have promised when the crucial moment comes.
宗祖日莲大圣人于《开目抄》曰:
我及我弟子，虽有诸难，若无疑心，自然得至佛界。勿疑天无加护，莫叹现世不安稳，虽朝夕教我弟子，皆生疑弃舍。愚人之习，约定之事，忘于关键之时。
