You can visit it. Not the mountain — nobody has located that — but its architecture, which has been built at full ceremonial scale on three continents. The five towers of Angkor Wat are its peaks. The stepped mass of Borobudur is its terraces. The shikhara over a north Indian sanctum and the vimana over a south Indian one are both, in their own manuals' language, mountains, and Balinese village shrines with their stacks of black thatched roofs are called meru outright. A cosmological idea became a building type and then became several national heritages.
What the Puranas say is at the centre
Puranic cosmology places Meru at the centre of everything. It is a golden mountain, immensely tall, wider at the summit than at the base, around which the sun and planets circle rather than passing overhead. Around it lies Jambudvipa, the rose-apple continent, and around that a ring ocean, and beyond that further ring continents and oceans of milk, curd, clarified butter and sugarcane juice, in a scheme that grows more elaborate with each retelling.
On the summit sit the cities of the gods: Brahma's in the centre, Indra's Amaravati and the seats of the other directional guardians around it. India — Bharatavarsha — sits to the south of the mountain, in the region where action produces consequences and where liberation is therefore available, which is a piece of cosmological patriotism the texts state quite openly.
The names multiply: Sumeru, the excellent Meru; Mahameru, the great; Hemadri, the golden peak.
Three religions, one axis
Meru is one of the very few features shared across all the Indian religions with essentially the same function.
- Buddhist cosmology has Sumeru with four continents at the cardinal points, humans inhabiting the southern one, and the heavens stacked above in a scheme worked out in immense numerical detail in the Abhidharma literature. It reaches China and Japan as Xumi and Shumisen.
- Jain cosmology places Meru at the centre of the middle world, and holds that the gods carry every newborn Tirthankara to its summit to be bathed in water from the ocean of milk — a scene depicted constantly in Jain painting and reenacted in temple ritual.
- Hindu Puranas supply the version above, with regional variations by text.
Because the mountain is shared, Meru is also the reason Hindu and Buddhist monuments across Southeast Asia look so alike. A temple is a model of the cosmos; the cosmos has a mountain at the middle; therefore a temple is a mountain, with the deity in the cave at its heart.
The mountain in stone
- Angkor Wat, twelfth century, has five towers in a quincunx representing Meru's peaks, surrounded by walls for the ring mountains and a moat for the cosmic ocean. Its churning-of-the-ocean relief runs some forty-nine metres along the east gallery.
- Prambanan in Java rises in a mass of steep towers to a central Shiva shrine; Borobudur ascends through terraces of relief panels to an open summit of stupas, a Buddhist Meru you climb.
- Indian temple manuals — the Shilpa and Vastu texts — name particular tower types Meru, Mandara and Kailasa, so the mountain is a technical term in the drawing office as well as a myth.
- Balinese meru shrines carry an odd number of tiered roofs, up to eleven, with the count assigned by deity.
A japa mala has a hundred and eight beads and one larger head bead called the meru or sumeru, which is not counted and not crossed; the practitioner reverses direction there. The mountain has ended up in the hand.
Where is it?
The tradition is not much interested in the question, but three answers circulate. Mount Kailash in western Tibet is widely identified with it or treated as its earthly counterpart, and its position at the source region of four great rivers — the Indus, the Sutlej, the Brahmaputra and the Karnali feeding the Ganges — gives that identification real geographical force. A second view treats Meru as the celestial pole, which fits the description of the stars wheeling around it and of a six-month day at the summit. A third treats it as purely a cosmological construct that was never meant to be on a map. The comparison of world-axes across traditions sets it beside the Norse tree and its equivalents.
The Puranic model and the mathematical astronomy of the Surya Siddhanta tradition, which computed eclipses accurately and worked with a spherical earth, coexisted in Indian intellectual life without either displacing the other. Indian astronomers were aware of the discrepancy and generally handled it by treating the two as different genres of knowledge — a settlement worth knowing before assuming that either the cosmology was naive or the astronomy was suppressed.
Questions the golden mountain raises
Is Mount Meru in Tanzania named after it?
No. The Tanzanian volcano's name comes from a local East African language and the coincidence is just that. The Indonesian volcano Semeru on Java, by contrast, is named directly from Sumeru and is regarded in Javanese tradition as a fragment of the cosmic mountain brought from India — a story recorded in the Old Javanese Tantu Pagelaran.
Was Meru the mountain used to churn the ocean?
No, and the confusion is very common. The churning-staff is Mandara, a different mountain, uprooted for the purpose and set on the back of the tortoise avatar to stop it sinking. Meru is the fixed centre and is never moved; some texts have Vishnu carry Mandara using Garuda, which is precisely the kind of task the axis of the world could not be asked to perform.
How tall is it supposed to be?
The Puranas give figures in yojanas — commonly 84,000 above ground and 16,000 below — and the length of a yojana is itself disputed, running anywhere from about seven to fifteen kilometres depending on the text and the interpreter. The numbers are best read as belonging to the same order of intention as the cycles of time: the point is a scale at which ordinary measurement stops applying.
Does the mandala relate to it?
Directly. A mandala's concentric enclosures around a centre are the same cosmological diagram in plan that the mountain is in elevation, which is why temple ground plans, ritual diagrams and Tibetan sand mandalas share a structure. Offering rites in Tibetan Buddhism include the symbolic presentation of the entire Meru cosmos, built up in rice on a metal plate and swept away afterwards.
