Hindu cosmology: the fourteen worlds and the ages of the universe

Read this sentence slowly. On the Hindu scale of time, nothing has happened.

One day of Brahmā, the creator, lasts 4.32 billion years. That is roughly the real age of the Earth. Brahmā is halfway through a life of a hundred such years, and when it closes the whole universe will fold back into its source, and another creator will wake in another egg and begin again. This has happened before. It will happen again. Nobody has counted the times.

And yet the oldest hymn in the entire tradition about how any of it began does not end in an answer. It ends in a shrug.

The hymn that will not answer

The Ṛgveda is the oldest layer of the record, roughly 1500 to 1000 BCE. Its tenth and latest book holds a handful of speculative hymns that reach for the origin of everything, and the most famous of them, the Nāsadīya Sūkta (Ṛgveda 10.129), reaches, looks, and refuses to close its hand.

को अद्धा वेद क इह प्र वोचत्कुत आजाता कुत इयं विसृष्टिः । अर्वाग्देवा अस्य विसर्जनेनाथा को वेद यत आबभूव ॥ इयं विसृष्टिर्यत आबभूव यदि वा दधे यदि वा न । यो अस्याध्यक्षः परमे व्योमन्सो अङ्ग वेद यदि वा न वेद ॥

ko addhā veda ka iha pra vocat, kuta ājātā kuta iyaṃ visṛṣṭiḥ arvāg devā asya visarjanenāthā ko veda yata ābabhūva

“Who really knows, and who can here declare it, whence it was born, whence came this creation? The gods are later than this world’s creation, so who truly knows from where it first arose. Whence this creation came to be, whether it was made or was not, the One who watches over it from the highest heaven, he alone knows, or perhaps even he does not know.”

Ṛgveda 10.129.6–7 #

That last clause is one of the boldest sentences in any scripture. The overseer in the highest heaven, and even he may not know. A. L. Basham called it a monument of humility. Carl Sagan, closing an episode of Cosmos in 1980, read it aloud as an example of a tradition willing to stand before the cosmic mysteries without flinching and without pretending.

Everything that follows in this account is a later, more confident architecture built over that opening honesty. It is worth keeping the honesty in view. The tradition itself put the question mark first.

The cosmic egg

The word for a single universe is brahmāṇḍa, the egg of Brahmā. The image is old. In Ṛgveda 10.121 a golden germ, Hiraṇyagarbha, “the golden womb”, floats on the primal waters and becomes the one lord of all that breathes. The Manusmṛti, the law book compiled around the turn of the Common Era, hardens the picture into a cosmogony: the Self-existent placed his seed in the waters, and “that seed became a golden egg, in brilliancy equal to the sun”, and inside it he was born as Brahmā, grandfather of the worlds (Manu 1.8 to 1.9, in G. Bühler’s translation). He rested in the egg a year, then split it, and from the two halves made heaven and earth.

There is a second, stranger image beside the egg. In the Puruṣa Sūkta (Ṛgveda 10.90) the world is offered into being rather than made. It is sacrificed out of the body of a cosmic Person.

सहस्रशीर्षा पुरुषः सहस्राक्षः सहस्रपात् । स भूमिं विश्वतो वृत्वात्यतिष्ठद्दशाङ्गुलम् ॥

sahasraśīrṣā puruṣaḥ sahasrākṣaḥ sahasrapāt sa bhūmiṃ viśvato vṛtvāty atiṣṭhad daśāṅgulam

“Puruṣa, who has a thousand heads, a thousand eyes, a thousand feet, investing the earth in all directions, exceeds it by a space measuring ten fingers.” (H. H. Wilson’s translation of Sāyaṇa’s reading.)

Ṛgveda 10.90.1 #

The commentator Sāyaṇa read “thousand” as simply “infinite”, and the Person as virāṭ, the universal spirit inside all things. Two seed pictures, then, at the very root: the world as an egg that hatches, and the world as a body that is offered. The Puranas would spend a thousand years elaborating both.

Fourteen worlds, seven above and seven below

The Vedic universe is small and clean. It has three worlds, the trailokya: earth, the mid-air, and the sky. Their names are the three vyāhṛtis, bhūr bhuvaḥ svaḥ, the “earth, atmosphere, heaven” that a practising Hindu still speaks aloud every day at the head of the Gāyatrī. The cosmology was recited before it was ever mapped.

The map grew. By the time of the Puranas, roughly 300 to 1000 CE, the three worlds have become fourteen, seven stacked upward and seven downward. The upper seven are bhūr, bhuvaḥ, svar, mahar, janar, tapar, and satya, the last also called Brahmaloka, the creator’s own realm. The lower seven are the talas: atala, vitala, sutala, talātala, mahātala, rasātala, and at the bottom pātāla.

One careful distinction, because popular accounts blur it. The seven lower talas are subterranean worlds, not places of punishment. The hells, the narakas ruled by Yama, are a separate register, a set of punitive realms where karmic debts are paid. Fall through the floor of the talas and you are in a different kind of place from the one below the floor of the world.

The scholar Deborah Soifer, tracing the history of the word, showed that loka slid over the centuries from “world” in the plain sense toward “a station a soul reaches”, a position won by karma. That shift matters, and we will come back to it. For now hold the shape: a vertical stack of worlds, and a scheme that visibly got taller with the centuries.

The mountain at the centre

At the middle of the earth-plane stands a mountain. The Viṣṇu Purāṇa, in H. H. Wilson’s 1840 translation, lays out the plan in one dense breath:

“The seven great insular continents are Jambu, Plakṣa, Śālmali, Kuśa, Krauñca, Śāka, and Puṣkara, surrounded severally by seven great seas, the sea of salt water, of sugar-cane juice, of wine, of clarified butter, of curds, of milk, and of fresh water. Jambu-dvīpa is in the centre of all these, and in the centre of this continent is the golden mountain Meru.”

Seven ring-shaped continents, each moated by a different ocean, arranged around a central island, and at that island’s heart the golden world-axis, Meru, “like the seed-cup of the lotus of the earth”. India, Bhārata, sits on the southern edge of the innermost ring.

Here is the catch in the tidy picture, and an honest account has to name it. This is a flat, Meru-centred disc of concentric rings, hundreds of millions of yojanas across. It is not a description of the spherical globe, and the Bhāgavata Purāṇa, which gives the most detailed version in its fifth canto, was never trying to describe one. What the reader does with that fact is exactly where the tradition splits. Literalist schools, the Gauḍīya lineage among them, hold that the Bhāgavata describes a real structure on a plane our instruments do not reach. The Advaita reading treats the whole map as vyāvahārika, true at the everyday level and dissolving under analysis. A third, modern reading takes the continents and oceans as a deliberate mandala, a diagram of states rather than a chart of land. The text supports being read in each of these ways. It does not settle the question for you.

A day of Brahmā

If the space is strange, the time is stranger, and far more precise. The clock is stated plainly in the Bhagavad Gītā (8.17):

सहस्रयुगपर्यन्तमहर्यद् ब्रह्मणो विदुः । रात्रिं युगसहस्रान्तां तेऽहोरात्रविदो जनाः ॥

sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ rātriṃ yuga-sahasrāntāṃ te ‘ho-rātra-vido janāḥ

“Those who truly know the day and night of Brahmā know his one day to span a thousand yuga-cycles, and his night to last a thousand yuga-cycles too.”

Bhagavad Gītā 8.17 #

One turn of the four ages, a mahāyuga, runs 4,320,000 years. The four yugas carry the arithmetic of how that figure is built. A thousand of those cycles make one day of Brahmā, a kalpa: 4.32 billion years, close enough to the measured age of the Earth to have made Sagan pause on camera. His night is as long again. He lives a hundred such years of such days, on the order of three hundred trillion of our years, and the Manusmṛti adds that even this is one beat in an endless series: “the creations and destructions of the world are numberless; sporting, as it were, the Supreme repeats this again and again” (Manu 1.80).

A word of caution the record demands. The scholar Luis González-Reimann has shown that this grand billion-year clock is itself a construction, assembled in the epic and Puranic period out of a divine-year multiplier, later than the Veda. The 4.32-billion coincidence is real and striking. It is also retrospective. The tradition built the number; it did not receive it from the sky.

Waking and sleeping

Between one day of Brahmā and the next comes a pralaya, a dissolution. The tradition counts four kinds, from the small to the total. The daily death of a creature is one. The naimittika comes at the end of each of Brahmā’s days, when the three worlds are unmade while he sleeps. The prākṛtika comes at the end of his whole life, when the entire egg is reabsorbed into prakṛti, unmanifest nature. The last, ātyantika, is not cosmic at all: it is the final release of a single soul, mokṣa, the only exit that does not loop back.

The Manusmṛti puts the rhythm in a single image: “when that divine one wakes, then this world stirs; when he slumbers tranquilly, then the universe sinks to sleep” (1.52). The Puranas give the sleep a form. Between the ages Viṣṇu lies in yoga-nidrā, cosmic sleep, on the coils of the serpent Ananta-Śeṣa, floating on the shoreless water, and from his navel the lotus rises again carrying the next Brahmā. The universe does not end. It exhales, and holds, and begins.

Countless eggs

And it is not the only universe. This is the image that startles first-time readers most, and it is genuinely old. The Brahma-vaivarta Purāṇa tells a parable, retold by the art historian Heinrich Zimmer and much loved since: a procession of ants crosses the floor of Indra’s palace, and a sage explains that each ant was, in some past cycle, an Indra of its own universe. “Who will search through the wide infinities of space to count the universes side by side, each containing its Brahmā, its Viṣṇu, its Śiva?” The Bhāgavata describes innumerable brahmāṇḍas, each sealed in seven elemental shells, each shell ten times the last, drifting like specks. Every egg has its own creator. Every creator thinks his is the only one.

The same mountain, other universes

There is a detail here that a beginner should meet early, because it corrects a common assumption. Meru and Jambudvīpa are not uniquely Hindu. They are a shared inheritance of ancient India, and the Buddhist and Jain traditions build their own universes on the same foundation stone.

Buddhist cosmology keeps Mount Sumeru at the centre and stacks thirty-one planes of existence around it, across three tiers of desire, form, and formlessness. But there is no creator anywhere in the scheme, and the goal, nirvāṇa, is said to lie in no loka at all, off the map entirely. Jain cosmology makes the universe itself eternal and creatorless, and gives it a body: the loka is shaped like a cosmic man standing with hands on hips, heavens in the chest, our world at the waist, hells in the legs, and empty space beyond the outline where nothing lives.

Set all three against the traditions further west, and the sharpest single line of Indian cosmology comes into focus. The Abrahamic universe is created once, from nothing, and runs forward to a single end. The Indian universe, in all three of its great traditions, is beginningless and cyclic. There is no first morning. There is no last night. There is only the breathing.

What the map is for

So what is a reader meant to do with fourteen worlds and a flat central mountain and a clock in the billions?

Return to Soifer’s small observation, that loka came to mean a station as much as a place. Read that way, the vertical map is a map of consciousness as much as of geography. The Gītā says the state of mind at the moment of death carries the soul to its answering world. The higher lokas are subtler conditions of being; the lower ones are denser. Later, the Tantric and haṭha-yoga traditions would fold the whole scheme inward and correlate the seven upper worlds with the seven centres of the subtle body, so that the cosmos becomes a diagram of the human interior. That inner reading is a later systematization, and honesty requires saying so; it is not stated in the Vedic hymns. But it follows the grain of the material, which always treated the outer worlds and the inner states as versions of one thing.

The Advaita masters went further and pulled the ground out entirely. The worlds are real, they held, in the way a dream is real to the dreamer: māyā, valid until you wake. The fourteen lokas, Meru, the ring-oceans, the billion-year days: all of it is the appearance that the one reality, Brahman, throws up and reabsorbs. The map is true at the level where maps are true.

Which returns us to the shrug at the beginning. The tradition drew the most elaborate cosmic map any civilization has produced, fourteen worlds, seven seas, a clock to rival the geologists’, countless universes side by side. And it kept, at the very root of that map, a hymn that admits the mapmaker may not know.

The map was never a claim to have seen the edge of things.

It was a way of standing under the sky, and not being made small by how large it is.
