Note: Nichiren writes: “[W]e do not see how our mind contains ten realms, 100 realms, 1,000 aspects, and 3,000 modes of existence, unless we see our reflection in the clear mirror of the Lotus Sūtra and writings of Grand Master T’ien-t’ai such as Great Concentration and Insight.” Nichiren then specifies where in the Sūtra we find the explanation.

QUESTION (13): Which parts of the Lotus Sutra are you referring to? How about T’ien-t’ai’s explanation of them?

ANSWER: The second “Expedients” chapter of the Lotus Sutra (fascicle 1) states that the purpose of the Buddhas appearing in the worlds was “to cause all living beings to open the gate to the insight of the Buddha.” This means that of the nine of the ten realms of living beings (excepting the realm of Buddhas), each embraces the realm of Buddhas. In the sixteenth chapter, “The Life Span of the Buddha,” the sutra also declares: “As I said before, it is immeasurably long since I, Śākyamuni Buddha, obtained Buddhahood. My life spans an innumerably and incalculably long period of time. Nevertheless, I am always here and I shall never pass away. Good men! The duration of my life, which I obtained by practicing the way of bodhisattvas, has not yet expired. It will last twice as long as the length of time as stated above.” This passage also shows that the nine realms are included in the realm of Buddhas.

The following passages in the Lotus Sutra also show that the ten realms of living beings embrace one another. It is said in the twelfth chapter, “Devadatta,” that after an incalculably long period of time, Devadatta will be a Buddha called “Heavenly King.” This shows the realm of Buddhas included in the realms of hells as it says that even a man as wicked as Devadatta, who had tried to kill the Buddha and had gone to hell, will be able to become a Buddha.

In the twenty-sixth chapter on the “Mystic Phrases,” the Buddha praises the ten female rāksasas demons such as Lambā saying, “Your merits will be immeasurable even when you protect the person who keeps only the name of the Lotus Sutra.” Since even these rāksasas demons in the realm of hungry spirits protect the practicer of the Lotus Sūtra, the ten realms, from hells up to the realm of Buddhas, are comprised in the realm of hungry spirits.

The “Devadatta” chapter states also that a daughter of a dragon king attained perfect enlightenment, proving the existence of the ten realms in the realm of beasts.

The tenth chapter, “The Teacher of the Dharma,” says that even a semi-god like Asura King Balin (a king of asura demons mentioned in the first “Introduction” chapter) will obtain Buddhahood if he rejoices for a moment at hearing a verse or a phrase of the Lotus Sutra. This shows that the ten realms are contained in the realm of asura demons.

It is stated in the second “Expedients” chapter: “Those who carve an image of the Buddha with proper physical characteristics in His honor have already attained the enlightenment of the Buddha,” showing that the realm of man includes the ten realms in it.

Then in the first “Introduction” and the third “A Parable” chapters, various gods such as the great King of the Brahma Heaven declare, “we also shall be able to become Buddhas,” proving that the ten realms are contained in the realm of gods.

In the third chapter, the Buddha assures Śāriputra, the wisest of His Śrāvaka disciples, that he will also attain Buddhahood in future life and will be called “Kekō (Flower Light) Buddha.” This confirms the existence of the ten realms in the realm of Śrāvaka.

The second chapter states that those monks and nuns who sought emancipation through the way of pratyekabuddha (without guidance of teachers by observing the principle of cause and effect) pressed their hands together in respect, wishing to hear the Perfect Way. This affirms the existence of the ten realms in the realm of pratyekabuddha.

It is written in the twenty-first chapter, “Divine Powers of the Buddha,” that bodhisattvas as numerous as particles of dust of 1,000 worlds, who had sprung up from underground, beseeched the Buddha for this true, pure, and great dharma, namely the Lotus Sutra. This verifies the existence of the ten realms in the realm of bodhisattvas.

Finally in the sixteenth chapter, the Buddha sometimes appears as a Buddha in the realm of Buddhas but at other times appears as some of the others who reside in the other nine realms. This indicates that the ten realms are included in the realm of Buddhas.

I’ve understood for some time that the “3,000 existences contained in one thought” was not explicitly mentioned in the Lotus Sūtra but was instead written “between the lines.” With this lengthy excerpt I see the lines between which I should look.
