Some of my disciples pretend to know the details of doctrines. They are mistaken. The odaimoku, Namu Myōhō Renge Kyō, is the essence of the Lotus Sūtra. It is like a human being’s spirit. If any other teachings were to be added to the odaimoku, it would be the cause of great trouble. It would be like the Empress marrying two Emperors or committing adultery. The teachings of the Lotus Sūtra did not spread far enough during the Ages of the True Dharma and the Semblance Dharma. This was because these periods were intended for other sūtras.

We are presently living in the Latter Age of Degeneration. The Lotus Sūtra and other sūtras are no longer efficacious in bringing about enlightenment. Only the odaimoku can accomplish this. This is not my arbitrary opinion. It was so-arranged by the Buddha, the Buddha of Many Treasures, various Buddhas from all over the universe, and numerous great bodhisattvas from beneath the earth such as Superior Practice Bodhisattva.

It is a serious mistake to mix other teachings with the odaimoku. For example, when the sun rises, we no longer need to use lamps. When it rains, the dew is of no use. A baby does not need any nourishment except for milk. We do not need to add supplements to effective medicine.

Deceived by Devadatta, King Ajātaśtru became an enemy of the Buddha but his Minister Jīvaka was devoted to the Buddha and continued to have faith, the merit of which seems to have helped King Ajātaśtru. In Buddhism there is an important teaching that virtue stored within will naturally rise to the surface. Never-Despising Bodhisattva in the Lotus Sūtra bowed to passersby, saying, “I have heartfelt respect for you.” The “Lion-Roaring Bodhisattva” chapter in the Nirvana Sūtra says that all sentient beings have the Buddha-nature. It is stated in the Awakening of Faith in Mahāyāna by Bodhisattva Aśvaghosa, “As the wisdom of enlightenment works within, delusions are exterminated and, in turn, the Dharma body of enlightenment appears.” The same is preached in the Treatise on the Stages of Yoga Practice written by Bodhisattva Maitreya. These passages all mean that the internally hidden virtue will spontaneously rise to the surface.

QUESTION: If someone chanted Namu Myōhō Renge Kyō without understanding its meaning will the benefit of understanding still be received?

ANSWER: When a baby nurses, it does not comprehend the taste; nevertheless, it receives the benefits of the milk naturally. Did anyone know the ingredients or formula for Jīvaka’s wondrous medicines? Water is without intent but it can extinguish fire; and even though fire consumes many things, can we say it does this deliberately? This is Nāgārjuna and T’ien-t’ai’s idea! I am merely repeating it.

QUESTION: Why don’t you encourage people to contemplate the three thousand existences contained in one thought, instead of only advocating the chanting of the daimoku?

ANSWER: The two characters in the name Japan bring together all 66 provinces, with all their people, animals, and wealth without a single exception. Likewise, don’t the two characters for India bring together all 70 of its countries? Miao-lê says, “As a summation of the whole sūtra the entirety of the Lotus Sūtra is included in the daimoku.” He also says, “By way of summary the ten realms or ten aspects are used to indicate the entirety of the 3,000 existences.” Bodhisattva Mañjuśrī and the Venerable Ānanda used the daimoku of Myōhō Renge Kyō to indicate the entirety of the teaching of the Lotus Sūtra in three assemblies over the period of the last eight years of the Buddha’s teaching; and to indicate that this is what they meant the sūtra begins with the words “Thus have I heard.”

When we worship gods or Buddhas, we begin with the phrase of “namu.” Namu is an Indian word that has come to mean “offering of life to Buddhas and gods” in China and Japan. Our social standing is determined in part by possessing a spouse and children, retainers, fiefs, and gold and silver, though some people do not have these. Regardless of whether we possess these or not, no one possesses treasure more precious than life. Accordingly, sages and wise men in the past have donated their lives to the Buddhas in order to attain Buddhahood.

That is to say, Young Ascetic in the Snow Mountains offered his own body to a demon in order to learn a holy teaching consisting of eight Chinese characters. Medicine King Bodhisattva burned his own elbow and offered it to the Lotus Sūtra as a light. In Japan, Prince Shōtoku peeled the skin of his own hand to write the Lotus Sūtra on it, and Emperor Tenchi burned his third finger as an offering to Śākyamuni Buddha. These are deeds of sages and wise men, which are impossible for us ordinary people to emulate.

Nevertheless, ordinary people can become Buddhas by fully understanding the meaning of the word of “kokorozashi (intention)” and practicing it. What is the intention? When we consider this in detail, it refers to the doctrine of spiritual contemplation. What does the doctrine of spiritual contemplation mean? It means the way of practicing the teaching of the Buddha according to the intent of the Buddha, not necessarily according to what is literally said in the sūtra. For example, if a man donates his only set of clothes, which he wears for the cause of the Lotus Sūtra, this is the same as peeling his own skin for the sake of the Dharma. Suppose there is a man during the time of a famine who offers to the Buddha the only food he has to stay alive for a day. This is the same as offering his life to the Buddha.

These offerings are as meritorious as the offering of an elbow by Medicine King Bodhisattva or the offering by Young Ascetic in the Snow Mountains of his own body to a demon. Therefore, we can say that the self-sacrificial offerings of sages are phenomenal whereas the offerings of ordinary people according to the intent of the Buddha are noumenal. The doctrine of offering, one of the six practices for bodhisattvas to attain enlightenment, preached in the Great Concentration and Insight, part seven, refers to this noumenal offering, i.e. the practice of offering according to the intent of the Buddha.

Life is fleeting! No matter how many powerful enemies join forces against you, do not retreat and never be afraid. Even if your head is sawed off, your torso pierced through with a spear, and your feet shackled and drilled with a gimlet, you should continue chanting “Namu Myōhō-renge-kyō” as long as you have life. If you die chanting it, Śākyamuni Buddha, the Buddha of Many Treasures, and Buddhas in manifestation throughout the universe will immediately come flying, lead you by the hand or carry you on their shoulders to Mt. Sacred Eagle as they had promised at the assembly on Mt. Sacred Eagle. At that moment, two sages (Bodhisattvas Medicine King and Brave Donor), two heavenly kings (World Holding and Vaiśravaṇa), and ten female rākṣasa demons will protect you, upholders of the Lotus Sūtra, and various gods and deities will hold up a canopy over your head, wave banners, guard you, and certainly will send you to the Jeweled Land of Tranquil Light. Is not this the utmost happiness?

[T]he two Buddhas, Śākyamuni and Many Treasures, are functions of the substance, that is the five characters of myō, hō, renge, and kyō. In other words, the Lotus Sūtra is the Original Buddha. “The Life Span of the Buddha” chapter of the Lotus Sūtra mentions the Buddha’s “hidden core and divine powers.” The hidden core of the World Honored One refers to the substance of the Original Buddha possessing the threefold body (Dharma Body, Reward Body, and Accommodative Body). The divine powers mean the three bodies of manifested Buddhas as functions of the Original Buddha (substance). Also, we unenlightened people can fundamentally be the Original Buddha with three bodies of the substance, and the Buddha’s three bodies are functions and manifestations of the Original Buddha. If this is true, although we believed that Śākyamuni Buddha provided the three virtues of master, teacher and parent to us, instead it was we unenlightened people who provide three virtues to the Buddha. The reason why we say this is based on T’ien-t’ai’s interpretation in the ninth fascicle of the Words and Phrases of the Lotus Sūtra that, “The Tathagata (Thus-come One) is a common term for all Buddhas in ten directions in the past, present, and future, two Buddhas (True Body and Accommodative Body), three Buddhas (Dharma Body, Reward Body, and Accommodative Body), the Original Buddha and Buddhas in manifestation.” In this annotation, the Original Buddha refers to unenlightened people and Buddhas in manifestation mean Buddhas. However, there is a difference between unenlightened people and enlightened Buddhas, and those people are unaware that both people and Buddhas originally possess the same threefold bodies either as substance or function.

It has been 2,200 years or so since the Buddha expounded the Lotus Sūtra. As the life span of human beings is short, there is no one still alive who was able to see the Buddha in person. The length of a day as well as the life span in the realm of heavenly beings, however, are so long that there exist numerous heavenly beings who listened to the Buddha preach the Lotus Sūtra. Fifty years for human beings is equivalent to one day and night for the Four Heavenly Kings. Passing the day and night in this way, with 30 days in a month and 12 months to a year they live altogether 500 years. Accordingly, 2,200 years or so in the human realm is equivalent to 44 days of the Four Heavenly Kings, and it has been only 44 days since the sun and moon and Vaiśravaṇa (Bishamon, one of the Four Heavenly Kings) saw the Buddha enter Nirvana. In other words, it has not been two months yet since the Buddha passed away. To such heavenly beings as Indra and the King of the Brahma Heaven it has been a month or so since the Buddha passed into Nirvana. How can they forget all about the vow they made before the Buddha, the great favor of the sūtra in which they attained Buddhahood, and abandon the practicers of the Lotus Sūtra in such a short span? When we think of things in this way, we are sure we can depend on these heavenly beings.

Accordingly, the prayer said by the practicer of the Lotus Sūtra will inevitably be fulfilled just as a sound is echoed, a shadow follows the body, the moon reflects upon the clear water, a water nymph invites the water, a magnet attracts iron, amber eliminates dust, and a clear mirror reflects the color of everything.

Although Śubh̄karasimha was such a splendid person, he once experienced a sudden death. Upon regaining consciousness, however, he is said to have declared:

Upon my death, a hell guard came to tie me with seven iron ropes, hit me hard with an iron stick, and dragged me to the palace of King Yama. Somehow I completely forgot all Buddhist scriptures said to be 80,000 in number, not remembering even one word or a phrase except the title of the Lotus Sūtra. When I recalled it, the iron ropes that tied me got loose somewhat. Breathing a sigh of relief, I recited a passage in the “Expedients” chapter of the Lotus Sūtra resoundingly: “This triple world is all My domain, in which all the living beings are my children without exception. Although there exist many sufferings and difficulties in this world, only I, the Buddha, alone can save and protect all living beings.” Then the seven iron ropes were broken into pieces and scattered all over. Seeing this scene, King Yama took off his crown, came down to the courtyard, and said to me, “This experience of death has not exhausted your entire life span.” Thus he sent me back to this world.

QUESTION: You cannot burn anything by simply uttering the word, “fire,” repeatedly. Indeed, you have to use your hand in order to burn something. You cannot quench your thirst by just saying “water.” You need to use your mouth for drinking water. The same is true with the daimoku. I doubt it is possible to escape from the evil realms through the mere chanting of the daimoku, Namu Myōhō Renge Kyō. Isn’t it necessary to understand what the daimoku means and what it entails?

ANSWER: When the sinew of a lion is used as a string for a koto, the sound is so powerful that all the strings made from other threads will snap. And when hearing of the sourness of a pickled plum, saliva fills the mouth without eating it. Such mysterious things happen even in worldly affairs. How then can it be denied that something wonderful happens with the Lotus Sūtra? Even a parrot is said to have been reborn in the realm of heavenly beings just by repeating the name of the Four Noble Truths of the Hinayāna teaching. Moreover, a man who dedicated himself to the Three Treasures – the Buddha, Dharma, and Saṃgha – was able to escape the attack of a monster fish in the ocean. Imagine the wonders that would occur with the daimoku of the Lotus Sūtra, the essence of all the 80,000 teachings, and the eye of all the Buddhas. Do you still hold the belief that you cannot escape the four kinds of evil realms by just chanting the daimoku of the Lotus Sūtra?
