Buddhist cosmology

Buddhist cosmology is the description of the shape and evolution of the Universe according to the Buddhist scriptures and commentaries.

It consists of temporal and spatial cosmology, the temporal cosmology being the division of the existence of a 'world' into four discrete moments (the creation, duration, dissolution, and state of being dissolved, this does not seem to be a canonical division however). The spatial cosmology consists of a vertical cosmology, the various planes of beings, their bodies, characteristics, food, lifespan, beauty etc. And a horizontal cosmology, the distribution of these world-systems into an "apparently" infinite sheet of universes. The existence of world-periods (moments, kalpas), is well attested to by the Buddha.[1][2]

It should be noted that the historical Buddha (Gautama Buddha) made references to the existence of aeons (which he describes the length of by metaphor[3]), and simultaneously intimates his knowledge of past events, such as the dawn of human beings in their coarse and gender-split forms,[4] the existence of there being more than one sun at certain points in time,[1] and his ability to convey his voice vast distances, as well as the ability of his disciples (who if they fare accordingly) to be reborn in any one of these planes (should they so choose)[5]—the Buddha does not seem to place a premium on figuring out cosmology.[6]

He also refused to answer questions regarding either the infinitude or eternity of the world.

Introduction

The self-consistent Buddhist cosmology which is presented in commentaries and works of Abhidharma in both Theravāda (31 planes, Sakwala Vibhanga) and Mahāyāna traditions, is the end-product of an analysis and reconciliation of cosmological comments found in the Buddhist sūtra and vinaya traditions. No single sūtra sets out the entire structure of the universe. Kalpa Vibhangaya However, in several sūtras the Buddha describes other worlds and states of being, and other sūtras describe the origin and destruction of the universe. The synthesis of these data into a single comprehensive system must have taken place early in the history of Buddhism, as the system described in the Pāli Vibhajyavāda tradition (represented by today's Theravādins) agrees, despite some minor inconsistencies of nomenclature, with the Sarvāstivāda tradition which is preserved by Mahāyāna Buddhists.[7]

The picture of the world presented in Buddhist cosmological descriptions cannot be taken as a literal description of the shape of the universe. It is inconsistent, and cannot be made consistent, with astronomical data that were already known in ancient India. However, it is not intended to be a description of how ordinary humans perceive their world;[7] rather, it is the universe as seen through the divyacakṣus (Pāli: dibbacakkhu), the "divine eye" by which a Buddha or an arhat who has cultivated this faculty can perceive all of the other worlds and the beings arising (being born) and passing away (dying) within them, and can tell from what state they have been reborn and into what state they will be reborn. The cosmology has also been interpreted in a symbolical or allegorical sense (for Mahayana teaching see Ten spiritual realms).

Buddhist cosmology can be divided into two related kinds: spatial cosmology, which describes the arrangement of the various worlds within the universe; and temporal cosmology, which describes how those worlds come into existence, and how they pass away.

Spatial cosmology

Spatial cosmology can also be divided into two branches. The vertical (or cakravāla) cosmology describes the arrangement of worlds in a vertical pattern, some being higher and some lower. By contrast, the horizontal (sahasra) cosmology describes the grouping of these vertical worlds into sets of thousands, millions or billions.

Vertical cosmology

In the vertical cosmology, the universe exists of many worlds (lokāḥ) – one might say "planes/realms" – stacked one upon the next in layers.Sakwala Vibhangaya[8] Each world corresponds to a mental state or a state of being. A world is not, however, a location so much as it is the beings which compose it; it is sustained by their karma and if the beings in a world all die or disappear, the world disappears too. Likewise, a world comes into existence when the first being is born into it. The physical separation is not so important as the difference in mental state; humans and animals, though they partially share the same physical environments, still belong to different worlds because their minds perceive and react to those environments differently.

The vertical cosmology is divided into thirty-one planes of existence and the planes into three realms, or dhātus, each corresponding to a different type of mentality. These three realms (Tridhātu) are the Ārūpyadhātu (4 Realms), the Rūpadhātu (16 Realms), and the Kāmadhātu (15 Realms). This Sakwala/solar system or plane of existence comprises the "five or six desire realms". In some instances all of the beings born in the Ārūpyadhātu and the Rūpadhātu are informally classified as "gods" or "deities" (devāḥ), along with the gods of the Kāmadhātu, notwithstanding the fact that the deities of the Kāmadhātu differ more from those of the Ārūpyadhātu than they do from humans. It is to be understood that deva is an imprecise term referring to any being living in a longer-lived and generally more blissful state than humans. Most of them are not "gods" in the common sense of the term, having little or no concern with the human world and rarely if ever interacting with it; only the lowest deities of the Kāmadhātu correspond to the gods described in many polytheistic religions.

The term "brahmā" is used both as a name and as a generic term for one of the higher devas. In its broadest sense, it can refer to any of the inhabitants of the Ārūpyadhātu and the Rūpadhātu. In more restricted senses, it can refer to an inhabitant of one of the eleven lower worlds of the Rūpadhātu, or in its narrowest sense, to the three lowest worlds of the Rūpadhātu (Plane of Brahma’s retinue) A large number of devas use the name "Brahmā", e.g. Brahmā Sahampati, Brahmā Sanatkumāra, Baka Brahmā, etc. It is not always clear which world they belong to, although it must always be one of the worlds of the Rūpadhātu. According to the Ayacana Sutta, Brahmā Sahampati, who begs the Buddha to teach Dhamma to the world, resides in the Śuddhāvāsa worlds.

Formless Realm (Ārūpyadhātu)

The Ārūpyadhātu (Sanskrit) or Arūpaloka (Pāli) (Tib: gzugs med pa'i khams; Jpn: 無色界 Mushiki-kai) or "Formless realm" would have no place in a purely physical cosmology, as none of the beings inhabiting it has either shape or location; and correspondingly, the realm has no location either. This realm belongs to those devas who attained and remained in the Four Formless Absorptions (catuḥ-samāpatti) of the arūpadhyānas in a previous life, and now enjoys the fruits (vipāka) of the good karma of that accomplishment. Bodhisattvas, however, are never born in the Ārūpyadhātu even when they have attained the arūpadhyānas.

There are four types of Ārūpyadhātu devas, corresponding to the four types of arūpadhyānas:

Arupa Bhumi (Arupachara Brahmalokas or Immaterial/Formless Brahma Realms)

Form Realm (Rūpadhātu)

The Rūpadhātu (Pāli: Rūpaloka; Tib: gzugs kyi khams; Jpn: 色界 Shiki-kai) or "Form realm" is, as the name implies, the first of the physical realms; its inhabitants all have a location and bodies of a sort, though those bodies are composed of a subtle substance which is of itself invisible to the inhabitants of the Kāmadhātu. According to the Janavasabha Sutta, when a brahma (a being from the Brahma-world of the Rūpadhātu) wishes to visit a deva of the Trāyastriṃśa heaven (in the Kāmadhātu), he has to assume a "grosser form" in order to be visible to them. There are 17-22 Rūpadhātu in Buddhism texts, the most common saying is 18.[9][10]

The beings of the Form realm are not subject to the extremes of pleasure and pain, or governed by desires for things pleasing to the senses, as the beings of the Kāmadhātu are. The bodies of Form realm beings do not have sexual distinctions.

Like the beings of the Ārūpyadhātu, the dwellers in the Rūpadhātu have minds corresponding to the dhyānas (Pāli: jhānas). In their case it is the four lower dhyānas or rūpadhyānas. However, although the beings of the Rūpadhātu can be divided into four broad grades corresponding to these four dhyānas, each of them is subdivided into further grades, three for each of the four dhyānas and five for the Śuddhāvāsa devas, for a total of seventeen grades (the Theravāda tradition counts one less grade in the highest dhyāna for a total of sixteen).

Physically, the Rūpadhātu consists of a series of planes stacked on top of each other, each one in a series of steps half the size of the previous one as one descends. In part, this reflects the fact that the devas are also thought of as physically larger on the higher planes. The highest planes are also broader in extent than the ones lower down, as discussed in the section on Sahasra cosmology. The height of these planes is expressed in yojanas, a measurement of very uncertain length, but sometimes taken to be about 4,000 times the height of a man, and so approximately 4.54 miles (7.31 km).

Pure Abodes

The Śuddhāvāsa (Pāli: Suddhāvāsa; Tib: gnas gtsang ma) worlds, or "Pure Abodes", are distinct from the other worlds of the Rūpadhātu in that they do not house beings who have been born there through ordinary merit or meditative attainments, but only those Anāgāmins ("Non-returners") who are already on the path to Arhat-hood and who will attain enlightenment directly from the Śuddhāvāsa worlds without being reborn in a lower plane. Every Śuddhāvāsa deva is therefore a protector of Buddhism. (Brahma Sahampati, who appealed to the newly enlightened Buddha to teach, was an Anagami from a previous Buddha[11]). Because a Śuddhāvāsa deva will never be reborn outside the Śuddhāvāsa worlds, no Bodhisattva is ever born in these worlds, as a Bodhisattva must ultimately be reborn as a human being.

Since these devas rise from lower planes only due to the teaching of a Buddha, they can remain empty for very long periods if no Buddha arises. However, unlike the lower worlds, the Śuddhāvāsa worlds are never destroyed by natural catastrophe. The Śuddhāvāsa devas predict the coming of a Buddha and, taking the guise of Brahmins, reveal to human beings the signs by which a Buddha can be recognized. They also ensure that a Bodhisattva in his last life will see the four signs that will lead to his renunciation.

The five Śuddhāvāsa worlds are:

Bṛhatphala worlds

The mental state of the devas of the Bṛhatphala worlds (Jpn: 四禅九天) corresponds to the fourth dhyāna, and is characterized by equanimity (upekṣā). The Bṛhatphala worlds form the upper limit to the destruction of the universe by wind at the end of a mahākalpa (see Temporal cosmology below), that is, they are spared such destruction.

Śubhakṛtsna worlds

The mental state of the devas of the Śubhakṛtsna worlds (Jpn: 三禅三天) corresponds to the third dhyāna, and is characterized by a quiet joy (sukha). These devas have bodies that radiate a steady light. The Śubhakṛtsna worlds form the upper limit to the destruction of the universe by water at the end of a mahākalpa (see Temporal cosmology below), that is, the flood of water does not rise high enough to reach them.

Ābhāsvara worlds

The mental state of the devas of the Ābhāsvara worlds (Jpn: 二禅三天) corresponds to the second dhyāna, and is characterized by delight (prīti) as well as joy (sukha); the Ābhāsvara devas are said to shout aloud in their joy, crying aho sukham! ("Oh joy!"). These devas have bodies that emit flashing rays of light like lightning. They are said to have similar bodies (to each other) but diverse perceptions.

The Ābhāsvara worlds form the upper limit to the destruction of the universe by fire at the end of a mahākalpa (see Temporal cosmology below), that is, the column of fire does not rise high enough to reach them. After the destruction of the world, at the beginning of the vivartakalpa, the worlds are first populated by beings reborn from the Ābhāsvara worlds.

Brahmā worlds
Main article: Brahma (Buddhism)

The mental state of the devas of the Brahmā worlds (Jpn: 初禅三天) corresponds to the first dhyāna, and is characterized by observation (vitarka) and reflection (vicāra) as well as delight (prīti) and joy (sukha). The Brahmā worlds, together with the other lower worlds of the universe, are destroyed by fire at the end of a mahākalpa (see Temporal cosmology below).

Desire Realm (Kāmadhātu)

Main article: Desire realm

The beings born in the Kāmadhātu (Pāli: Kāmaloka; Tib: 'dod pa'i khams; Jpn: 欲界 Yoku-kai) differ in degree of happiness, but they are all, other than Anāgāmi, Arhat and Buddhas, under the domination of Māra and are bound by sensual desire, which causes them suffering.

Heavens

The following four worlds are bounded planes, each 80,000 yojanas square, which float in the air above the top of Mount Sumeru. Although all of the worlds inhabited by devas (that is, all the worlds down to the Cāturmahārājikakāyika world and sometimes including the Asuras) are sometimes called "heavens", in the western sense of the word the term best applies to the four worlds listed below:

Worlds of Sumeru
Main article: Sumeru

The world-mountain of Sumeru is an immense, strangely shaped peak which arises in the center of the world, and around which the Sun and Moon revolve. Its base rests in a vast ocean, and it is surrounded by several rings of lesser mountain ranges and oceans. The three worlds listed below are all located on, or around, Sumeru: the Trāyastriṃśa devas live on its peak, the Cāturmahārājikakāyika devas live on its slopes, and the Asuras live in the ocean at its base. Sumeru and its surrounding oceans and mountains are the home not just of these deities, but also vast assemblies of beings of popular mythology who only rarely intrude on the human world.

Earthly realms
Hells (Narakas)
Main article: Naraka (Buddhism)

Naraka or Niraya (Tib: dmyal ba) is the name given to one of the worlds of greatest suffering, usually translated into English as "hell" or "purgatory". As with the other realms, a being is born into one of these worlds as a result of his karma, and resides there for a finite length of time until his karma has achieved its full result, after which he will be reborn in one of the higher worlds as the result of an earlier karma that had not yet ripened. The mentality of a being in the hells corresponds to states of extreme fear and helpless anguish in humans.

Physically, Naraka is thought of as a series of layers extending below Jambudvīpa into the earth. There are several schemes for counting these Narakas and enumerating their torments. One of the more common is that of the Eight Cold Narakas and Eight Hot Narakas.

Cold Narakas

Each lifetime in these Narakas is twenty times the length of the one before it.

Hot Narakas

The foundations of the earth

All of the structures of the earth, Sumeru and the rest, extend downward to a depth of 80,000 yojanas below sea level – the same as the height of Sumeru above sea level. Below this is a layer of "golden earth", a substance compact and firm enough to support the weight of Sumeru. It is 320,000 yojanas in depth and so extends to 400,000 yojanas below sea level. The layer of golden earth in turn rests upon a layer of water, which is 8,000,000 yojanas in depth, going down to 8,400,000 yojanas below sea level. Below the layer of water is a "circle of wind", which is 16,000,000 yojanas in depth and also much broader in extent, supporting 1,000 different worlds upon it. yojanas are equivalent to about 13 km (8 mi)

Sahasra cosmology

Sahasra means "one thousand". All of the planes, from the plane of neither perception nor non-perception (nevasanna-asanna-ayatana) down to the Avici – the "uninterruped" or "unceasing" (avici literally means "without interval") niraya – constitutes the single world-system, cakkavala (intimating something circular, a "wheel", but the etymology is uncertain[13]), described above. In modern parlance it would be called a 'universe', or 'solar system'.

A collection of one thousand solar systems are called a "thousandfold minor world-system" (culanika lokhadhatu). Or small chiliocosm.

A collection of 1,000 times 1,000 world-systems (one thousand squared) is a "thousandfold to the second power middling world-system" (dvisahassi majjhima lokadhatu). Or medium dichiliocosm.

The largest grouping, which consists of one thousand cubed world-systems, is called the "tisahassi mahasassi lokadhatu". Or great trichiliocosm.

The Tathagata, if he so wished, could effect his voice throughout a great trichiliocosm. He does so by suffusing the trichiliocosm with his radiance, which at the point the inhabitants of those world-system will perceive this light, and then proceeds to extend his voice throughout that realm.[14]

Maha Kalpa

The word kalpa, means 'moment'. A maha kalpa consists of four moments (kalpa), the first of which is creation. The creation moment consists of the creation of the "receptacle", and the descent of beings from higher realms into more coarse forms of existence. During the rest of the creation moment, the world is populated. Human beings who exist at this point have no limit on their lifespan. The second moment is the duration moment, the start of this moment is signified by the first sentient being to enter hell (niraya), the hells and nirayas not existing or being empty prior to this moment. The duration moment consists of twenty "intermediate" moments (antarakappas), which unfold in a drama of the human lifespan descending from 80,000 years to 10, and then back up to 80,000 again. The interval between 2 of these "intermediate" moments is the "seven day purge", in which a variety of humans will kill each other (not knowing or recognizing each other), some humans will go into hiding. At the end of this purge, they will emerge from hiding and repopulate the world. As of May 2015, it seems the lifespan of humans is 80 years, during the time of Gotama Buddha it was 100 years.[15][16] After this purge, the lifespan will increase to 80,000, reach its peak and descend, at which point the purge will happen again.

Within the duration 'moment', this purge and repeat cycle seems to happen around 18 times, the first "intermediate" moment consisting only of the descent from 80,000—the second intermediate moment consisting of a rise and descent, and the last consisting only of an ascent.

After the duration 'moment' is the dissolution moment, the hells will gradually be emptied, as well as all coarser forms of existence. The beings will flock to the form realms (rupa dhatu), a destruction of fire occurs, sparing everything from the realms of the 'radiant' gods and above (abha deva).

After 7 of these destructions by 'fire', a destruction by water occurs, and everything from the realms of the 'pleasant' gods and above is spared (subha deva).

After 64 of these destructions by fire and water, that is—56 destructions by fire, and 7 by water—a destruction by wind occurs, this eliminates everything below the realms of the 'fruitful' devas (vehapphala devas, literally of "great fruit"). The pure abodes (suddhavasa, meaning something like pure, unmixed, similar to the connotation of "pure bred German shepherd"), are never destroyed. Although without the appearance of a Buddha, these realms may remain empty for a long time. It should be noted that the inhabitants of these realms have exceedingly long life spans.

The formless realms are never destroyed because they do not consist of form (rupa). The reason the world is destroyed by fire, water and wind, and not earth is because earth is the 'receptacle'.

After the dissolution moment, this particular world system remains dissolved for a long time, this is called the 'empty' moment, but the more accurate term would be "the state of being dissolved". The beings that inhabited this realm formerly will migrate to other world systems, and perhaps return if their journeys lead here again.[17][18]

Temporal cosmology

Buddhist temporal cosmology describes how the universe comes into being and is dissolved. Like other Indian cosmologies, it assumes an infinite span of time and is cyclical. This does not mean that the same events occur in identical form with each cycle, but merely that, as with the cycles of day and night or summer and winter, certain natural events occur over and over to give some structure to time.

The basic unit of time measurement is the mahākalpa or "Great Eon" (Jpn: 大劫 daigō). The length of this time in human years is never defined exactly, but it is meant to be very long, to be measured in billions of years if not longer.

A mahākalpa is divided into four kalpas or "eons" (Jpn: 劫 ), each distinguished from the others by the stage of evolution of the universe during that kalpa. The four kalpas are:

Each one of these kalpas is divided into twenty antarakalpas (Pāli: antarakappa; Jpn: 中劫, "inside eons") each of about the same length. For the Saṃvartasthāyikalpa this division is merely nominal, as nothing changes from one antarakalpa to the next; but for the other three kalpas it marks an interior cycle within the kalpa.

Vivartakalpa

The Vivartakalpa begins with the arising of the primordial wind, which begins the process of building up the structures of the universe that had been destroyed at the end of the last mahākalpa. As the extent of the destruction can vary, the nature of this evolution can vary as well, but it always takes the form of beings from a higher world being born into a lower world. The example of a Mahābrahmā being the rebirth of a deceased Ābhāsvara deva is just one instance of this, which continues throughout the Vivartakalpa until all the worlds are filled from the Brahmaloka down to Naraka. During the Vivartakalpa the first humans appear; they are not like present-day humans, but are beings shining in their own light, capable of moving through the air without mechanical aid, living for a very long time, and not requiring sustenance; they are more like a type of lower deity than present-day humans are.[19]

Over time, they acquire a taste for physical nutriment, and as they consume it, their bodies become heavier and more like human bodies; they lose their ability to shine, and begin to acquire differences in their appearance, and their length of life decreases. They differentiate into two sexes and begin to become sexually active. Then greed, theft and violence arise among them, and they establish social distinctions and government and elect a king to rule them, called Mahāsammata, "the great appointed one". Some of them begin to hunt and eat the flesh of animals, which have by now come into existence.[20]

Vivartasthāyikalpa

First antarakalpa

The Vivartasthāyikalpa begins when the first being is born into Naraka, thus filling the entire universe with beings. During the first antarakalpa of this eon, human lives are declining from a vast but unspecified number of years (but at least several tens of thousands of years) toward the modern lifespan of less than 100 years. At the beginning of the antarakalpa, people are still generally happy. They live under the rule of a universal monarch or "wheel-turning king" (Sanskrit: cakravartin; Jpn: 転輪聖王 Tenrin Jō-ō), who conquer. The Mahāsudassana-sutta (DN.17) tells of the life of a cakravartin king, Mahāsudassana (Sanskrit: Mahāsudarśana) who lived for 336,000 years. The Cakkavatti-sīhanāda-sutta (DN.26) tells of a later dynasty of cakravartins, Daḷhanemi (Sanskrit: Dṛḍhanemi) and five of his descendants, who had a lifespan of over 80,000 years. The seventh of this line of cakravartins broke with the traditions of his forefathers, refusing to abdicate his position at a certain age, pass the throne on to his son, and enter the life of a śramaṇa. As a result of his subsequent misrule, poverty increased; as a result of poverty, theft began; as a result of theft, capital punishment was instituted; and as a result of this contempt for life, murders and other crimes became rampant.

The human lifespan now quickly decreased from 80,000 to 100 years, apparently decreasing by about half with each generation (this is perhaps not to be taken literally), while with each generation other crimes and evils increased: lying, greed, hatred, sexual misconduct, disrespect for elders. During this period, according to the Mahāpadāna-sutta (DN.14) three of the four Buddhas of this antarakalpa lived: Krakucchanda Buddha (Pāli: Kakusandha), at the time when the lifespan was 40,000 years; Kanakamuni Buddha (Pāli: Konāgamana) when the lifespan was 30,000 years; and Kāśyapa Buddha (Pāli: Kassapa) when the lifespan was 20,000 years.

Our present time is taken to be toward the end of the first antarakalpa of this Vivartasthāyikalpa, when the lifespan is less than 100 years, after the life of Śākyamuni Buddha (Pāli: Sakyamuni), who lived to the age of 80.

The remainder of the antarakalpa is prophesied to be miserable: lifespans will continue to decrease, and all the evil tendencies of the past will reach their ultimate in destructiveness. People will live no longer than ten years, and will marry at five; foods will be poor and tasteless; no form of morality will be acknowledged. The most contemptuous and hateful people will become the rulers. Incest will be rampant. Hatred between people, even members of the same family, will grow until people think of each other as hunters do of their prey.[21]

Eventually a great war will ensue, in which the most hostile and aggressive will arm themselves and go out to kill each other. The less aggressive will hide in forests and other secret places while the war rages. This war marks the end of the first antarakalpa.[22]

Second antarakalpa

At the end of the war, the survivors will emerge from their hiding places and repent their evil habits. As they begin to do good, their lifespan increases, and the health and welfare of the human race will also increase with it. After a long time, the descendants of those with a 10-year lifespan will live for 80,000 years, and at that time there will be a cakravartin king named Saṅkha. During his reign, the current bodhisattva in the Tuṣita heaven will descend and be reborn under the name of Ajita. He will enter the life of a śramaṇa and will gain perfect enlightenment as a Buddha; and he will then be known by the name of Maitreya (Pāli: Metteyya).

After Maitreya's time, the world will again worsen, and the lifespan will gradually decrease from 80,000 years to 10 years again, each antarakalpa being separated from the next by devastating war, with peaks of high civilization and morality in the middle. After the 19th antarakalpa, the lifespan will increase to 80,000 and then not decrease, because the Vivartasthāyikalpa will have come to an end.

Saṃvartakalpa

The Saṃvartakalpa begins when beings cease to be born in Naraka. This cessation of birth then proceeds in reverse order up the vertical cosmology, i.e., pretas then cease to be born, then animals, then humans, and so on up to the realms of the deities.

When these worlds as far as the Brahmaloka are devoid of inhabitants, a great fire consumes the entire physical structure of the world. It burns all the worlds below the Ābhāsvara worlds. When they are destroyed, the Saṃvartasthāyikalpa begins.

Saṃvartasthāyikalpa

There is nothing to say about the Saṃvartasthāyikalpa, since nothing happens in it below the Ābhāsvara worlds. It ends when the primordial wind begins to blow and build the structure of the worlds up again.

Other destructions

The destruction by fire is the normal type of destruction that occurs at the end of the Saṃvartakalpa. But every eighth mahākalpa, after seven destructions by fire, there is a destruction by water. This is more devastating, as it eliminates not just the Brahma worlds but also the Ābhāsvara worlds.

Every sixty-fourth mahākalpa, after fifty six destructions by fire and seven destructions by water, there is a destruction by wind. This is the most devastating of all, as it also destroys the Śubhakṛtsna worlds. The higher worlds are never destroyed.

Mahayana views

Mahayana Buddhism accepts the cosmology as above.[23][24] A cosmology with some difference is further explained in Chapter 5 of the Avatamsaka Sutra.
