First
One Is Enough
In one world, one buddha is enough to guide everyone. So a second is not needed.
Yakushi, Amitābha, Kannon, Jizō, Mahāvairocana. As you visit the temples of Japan, you meet the names of many buddhas.
There is a clear reason for this. The key is the teaching of "one buddha per land" (ichibutsu ikkokudo): in one world, there is one buddha.
Buddhism has two great streams: sectarian (Nikāya) Buddhism and Mahāyāna Buddhism.
Over the long years after Śākyamuni passed away, Buddhism divided into these two streams. The first, sectarian Buddhism, is the older stream, which keeps and hands down a form close to the early teaching. Theravāda Buddhism, practiced today in Sri Lanka, Thailand, and Myanmar, is its main representative.
The other, Mahāyāna Buddhism, arose a little later and aspires to save all living beings together. It reached Japan by way of China and the Korean peninsula, and the Buddhism of the temples where we pray today is this Mahāyāna Buddhism.
In one world, at one time, two buddhas do not appear.
Sectarian Buddhism and Mahāyāna Buddhism both inherited this rule in the same way.
Why, then, is one buddha enough? The old sutras set a buddha beside a king: just as two kings do not rule one realm side by side, two buddhas do not exist together. The Questions of King Milinda also answers that if two buddhas appeared at once, disputes would arise among their disciples over "your buddha" and "our buddha." To guide one world, one buddha was thought to be enough.
Though the rule is the same, from here Buddhist views divide in two. The dividing point is whether the world is seen as this one only, or as countless.
If you count one world, there is one buddha. If you count countless worlds, there is a buddha in each of them, and the buddhas too are countless.
This difference in the number of worlds separated a Buddhism that looks to Śākyamuni alone from a Buddhism that looks to countless buddhas, beginning with Amitābha and Yakushi.
世界の数で、仏教は分かれる
Early sectarian Buddhism saw the world as "this one only."
The buddha present in this world now is Śākyamuni alone. This view does not teach that buddhas are present in other worlds. Śākyamuni was born in India some 2,500 years ago and attained awakening. Sectarian Buddhism hands down the teaching of this one buddha, Śākyamuni.
This "one world" is very large. A world with Mount Sumeru (Shumisen) at its center, ringed by continents and seas, is counted as one small world. A thousand of these, times a thousand, times a thousand again, make a great trichiliocosm (sanzen daisen sekai): one billion small worlds.
This whole great trichiliocosm is the land of a single buddha. Its billion small worlds are taken together as one land, called a buddha-field (ichi bussetsu).
The great trichiliocosm in which we live is called the Sahā world (Shaba). The buddha who guides this world, its teaching lord (kyōshu), is Śākyamuni. "In one world there is one buddha" means that Śākyamuni alone is responsible for this entire vast world.
Sectarian texts state this view clearly. The southern Theravāda in the Kathāvatthu (Points of Controversy), and the northern Sarvāstivāda in the Nyāyānusāra, both reject the claim that "buddhas are now present in other worlds as well." Since the world is this one only, the present buddha is Śākyamuni alone.
「1つの世界」の大きさ
小さな世界を1000倍し、また1000倍、さらに1000倍。
Mahāyāna Buddhism saw this world as "one among countless worlds."
Each of the countless worlds is the size of a great trichiliocosm, and each has its own buddha. Mahāyāna held that Śākyamuni is present in our Sahā world, Amitābha in the Land of Bliss (Gokuraku) far to the west, and Yakushi in the Pure Lapis Lazuli world (Jōruri) far to the east.
Here is the answer to our opening question. The buddhas we meet at Japanese temples are each, originally, the lord of a different world. Amitābha is the buddha of the Land of Bliss, Yakushi of the Pure Lapis Lazuli world, and Akṣobhya (Ashuku) of the eastern world of Abhirati (Myōki). Because their worlds differ, there is no contradiction in their being present at the same time.
Why, then, can we worship the buddhas of other worlds at temples here in the Sahā world? Because the buddhas of other worlds appear in this world in provisional forms to save its people. This is called manifestation (jigen). So Amitābha and Yakushi, while being lords of other worlds, work for us now as the principal images before our eyes.
The Mahāyāna sutras describe these countless buddhas. The Sukhāvatīvyūha (Muryōju-kyō) teaches the Land of Bliss, the Yakushi Sutra teaches the Pure Lapis Lazuli world, and the Lotus Sutra teaches the eternal Śākyamuni.
Countless worlds, countless buddhas. In time, the Mahāyāna sutras came to teach of a buddha who pervades all these worlds.
The leading example is Vairocana (Birushana) of the Avataṃsaka Sūtra (Kegon-kyō). Also called Rushana, this buddha is the Great Buddha of Tōdaiji in Nara. He is taught to be the buddha whose body is all the countless worlds.
The pedestal of the Great Buddha of Tōdaiji depicts this buddha's world. On each petal of the great lotus on which the Great Buddha sits, Mount Sumeru and the heavens are finely engraved. This is the world taught in the Brahmā's Net Sūtra (Bonmō-kyō). According to that sutra, a thousand Śākyamunis appear on the thousand petals surrounding the lotus pedestal. On each petal are ten billion lands, and in each land one Śākyamuni becomes a buddha ("one flower, ten billion lands; one land, one Śākyamuni"). The rule of one buddha per world holds here too. And all those countless Śākyamunis are the body of the one Rushana ("Rushana is the original body").
Esoteric Buddhism calls this buddha Mahāvairocana (Dainichi Nyorai). "Dainichi" renders Mahāvairocana, "the great Vairocana." If all worlds are taken together as one world, the buddha present there is also one. That buddha is Mahāvairocana. Mahāvairocana has as his body the whole of the worlds, the Dharma-realm (hokkai), and expounds the teaching unceasingly, in every place and at every time.
The Sūtra of Contemplating Samantabhadra (Kanfugen-gyō) says, "Śākyamuni is called Vairocana, pervading all places." The true body of the buddha that fills the Dharma-realm is called the dharmakāya (hosshin). Mahāvairocana is this dharmakāya buddha. The form Mahāvairocana shows in response to our world is called the responsive body (ōjin), and that is Śākyamuni. The Śākyamuni before us and Mahāvairocana are two forms of the same buddha. Kōbō Daishi Kūkai understood the Rushana of the Avataṃsaka in a new light, as the dharmakāya buddha who himself expounds the teaching.
「1つの世界」をどこまでと見るか
What reached Japan was this Mahāyāna Buddhism. That is why Japanese temples enshrine so many buddhas.
Amitābha, Yakushi, Mahāvairocana, the historical Śākyamuni: there is no contradiction in enshrining them together in one temple. Japanese Buddhism stands on the Mahāyāna view that "there are as many buddhas as there are worlds."
On the Shikoku 88-temple pilgrimage, the principal image differs from temple to temple: Yakushi, Mahāvairocana, Kannon, Jizō. To go from one to the next, worshipping each, is also to walk within the Mahāyāna teaching that "there are as many buddhas as there are worlds."
Byodoji is a temple of the Kōyasan Shingon school and Temple 22 of the Shikoku Pilgrimage. The Shingon school reveres Mahāvairocana, who pervades all worlds, as the source of all buddhas. Mahāvairocana is the buddha who unites every virtue in one; this is called fumon sōtai, the all-encompassing whole. Byodoji enshrines as its principal image Yakushi of the eastern Pure Lapis Lazuli world, the buddha who expresses one of those virtues. This is called ichimon betsutoku, one gate with its particular virtue.
Kōbō Daishi also taught attaining buddhahood in this very body (sokushin jōbutsu): becoming a buddha just as one is. We are connected with Mahāvairocana from the very beginning. Joining the hands, reciting mantras (shingon), and turning the heart toward the buddha: these acts of body, speech, and mind are called the three secrets (sanmitsu), and it is taught that through the practice of the three secrets, awakening quickly appears.
Countless worlds, countless buddhas. In the Shingon school, this leads to the teaching of attaining buddhahood in this very body, becoming a buddha just as one is. What follows is a supplement for readers who want to confirm this in the words of the original texts.
「仏さまは何人おられるか」という問いは、やがて「私の心のうちに、仏さまをどう見いだすか」という問いへと深まっていきます。
Later scholar-monks summed up the reasons why there is one buddha per world in four points.
First
In one world, one buddha is enough to guide everyone. So a second is not needed.
Second
During his practice before becoming a buddha, he vowed to become the refuge of beings in a world that had no other guide. So he does not appear again in a world where a buddha is already present.
Third
Precisely because there is only one, people feel deep reverence, thinking, "This is a precious one, rarely met."
Fourth
Knowing that such a meeting is rare, people resolve, "Let me strive in the teaching now."
This teaching survives in nearly the same words in sutras in four languages: Pali, Sanskrit, Chinese, and Tibetan. First, the words of the sutras of the oldest layer.
aṭṭhānam etaṃ anavakāso yaṃ ekissā lokadhātuyā dve arahanto sammāsambuddhā apubbaṃ acarimaṃ uppajjeyyuṃ, netaṃ ṭhānaṃ vijjati.
阿難、若世中有二轉輪王並治者、終無是處。阿難、若世中有二如來者、終無是處。
我從佛聞、親從佛受、欲使一時二佛出世、無有是處。
Kena kāraṇena dve tathāgatā ekakkhaṇe nuppajjanti? Ayaṃ, mahārāja, dasasahassī lokadhātu ekabuddhadhāraṇī, ekasseva tathāgatassa guṇaṃ dhāreti. Yadi dutiyo buddho uppajjeyya, nāyaṃ dasasahassī lokadhātu dhāreyya, caleyya kampeyya nameyya onameyya vinameyya vikireyya vidhameyya viddhaṃseyya, na ṭhānamupagaccheyya.
如一中千世界、爾所中千千世界、是為三千大千世界。如是世界周匝成敗、眾生所居名一佛剎。
Next come the treatises of the various schools. Each school explains the same teaching with reasons, and from there they divide into the Theravāda and Sarvāstivāda, which see the world as one only, and the Mahāyāna, which sees countless worlds.
First, the Sarvāstivāda, which flourished in the north, set out with reasons why two buddhas do not appear at the same time.
又問、何因二佛如來・應供・正等正覺不同時出。答、菩薩往昔修因其事廣大、謂於長時、唯一師教・一種修習、作諸善法、隨其所作同一解脱・唯一所尊・唯一大智。作諸善業、長養成熟、於一時中無二果報現前所起。此復云何。答、二難並故。以是因故、於一時中二佛如來・應供・正等正覺不同出世。
若爾、何故一世界中無二如來俱時出現。以無用故、謂一界中一佛、足能饒益一切。又願力故、謂諸如來爲菩薩時先發誓願、願我當在無救無依盲闇界中成等正覺、利益安樂一切有情、爲救爲依爲眼爲導。又令敬重故、謂一界中唯有一如來便深敬重。又令速行故、謂令如是知一切智尊甚爲難遇、彼所立教應速修行、勿般涅槃或往餘處、便令我等無救無依。故一界中無二佛現。

Finally, words from the Mahāyāna sutras that lead to Vairocana and Mahāvairocana.
一一毛孔中、一切剎塵諸佛坐、菩薩眾會共圍遶、演説普賢之勝行。

盧舍那佛神力故、一切剎中轉法輪(中略)法身堅固不可壞、充滿一切諸法界、普能示現諸色身、隨應化導諸群生。
我今盧舍那、方坐蓮花臺、周匝千花上、復現千釋迦。一花百億國、一國一釋迦、各坐菩提樹、一時成佛道。如是千百億、盧舍那本身。

Because the Mahāyāna Buddhism that reached Japan holds that "there are countless worlds, and a buddha in each of them." Buddhas of different worlds, such as Amitābha of the western Land of Bliss and Yakushi of the eastern Pure Lapis Lazuli world, are enshrined together in one temple.
No. The rule of "one buddha per world" concerns a single world. Śākyamuni is the buddha of this world; Amitābha of the western Land of Bliss and Yakushi of the eastern Pure Lapis Lazuli world are buddhas of other worlds. Because their worlds differ, there is no problem in their being present at the same time.
Mahāyāna Buddhism does not think so. "One" means that two buddhas are not present at the same time in the same world; in other worlds, countless buddhas are present now. The older schools such as the Theravāda and the Sarvāstivāda, however, held strictly that the only buddha present now is Śākyamuni.
Maitreya is the one who will appear in this world as a buddha after Śākyamuni. This concerns time, one buddha after another in the same world, and is a separate matter from the presence of many buddhas now in other worlds.
"Hīnayāna" ("Lesser Vehicle") was originally a name the Mahāyāna side used to look down on others; today we say sectarian (Nikāya) Buddhism or Theravāda Buddhism. Sectarian and Mahāyāna Buddhism inherited the rule of "one buddha per world" in the same way. The difference is whether the world is seen as "this one only" or as "one among countless worlds."
This article was prepared by Taniguchi Shinryō, head priest of Byodoji, Kōyasan Shingon school, on the basis of the following primary texts and materials. The Chinese-language scriptures and treatises are verified against the Taishō Revised Tripiṭaka (CBETA; Kūkai's compositions via the SAT Daizōkyō Text Database), the Pali against the original texts of the southern transmission (PTS editions), the Sanskrit against critical editions, and the Tibetan translations against the base text of the Derge Tengyur. "No." refers to the sūtra or treatise number in the Taishō Revised Tripiṭaka, and "Toh" to the Tōhoku University catalogue number of the Derge Tengyur.
