The mountain · What it is
What is Arunachala? The mountain that is fire
Not a hill with a temple on it, but a hill held to be God himself ~ the element of fire, cooled into a form a person can walk around and love. The legend, the antiquity, and why Arunachala is worshipped as the mountain itself.

It takes most visitors a little while to understand what people here mean when they speak of the mountain. They do not quite mean a place of pilgrimage, though it is one; nor a beautiful view, though it is that too. They mean something stranger and more absolute: that the hill itself is Shiva ~ not a symbol of the god, not the god's dwelling, but his actual form, taken deliberately so that human beings might have something they could approach, and walk around, and love. To understand Arunachala at all is to sit with that claim, whether or not you come to believe it.
Physically, Arunachala is unremarkable enough to describe: a roughly conical hill of about eight hundred metres, rising alone from the plain at the western edge of the town of Tiruvannamalai, in the north of the South Indian state of Tamil Nadu. What is not unremarkable is what has gathered around it ~ a great temple at its foot, a fourteen-kilometre road of pilgrimage around its base, a body of scripture devoted to its glory, and the quiet, absolute devotion of the millions who regard it as the most sacred ground on earth.
The mountain of fire
Arunachala is counted among the Pancha Bhuta Sthalams ~ the five temples of the elements, each sacred to Shiva in one of the five forms of matter: earth, water, fire, air, and space. Arunachala is the temple of fire (Agni). This is not a decorative association. The whole meaning of the hill flows from it, and the great legend of Arunachala is a story about fire.
The column of light
The founding story is told in the Arunachala Mahatmyam, the "Glory of Arunachala," preserved in the old Sanskrit texts and published in translation by Sri Ramanasramam. It runs, in essence, like this.
In the beginning, Brahma the creator and Vishnu the preserver ~ both arisen from the supreme Shiva ~ fell to quarrelling over which of them was the greater. Their dispute grew so fierce that it threatened the order of the universe itself. To end it, Shiva appeared between them not as a figure but as an infinite column of fire, a shaft of blazing light stretching beyond sight in both directions, without beginning or end.
The two gods agreed to test their greatness against it: whoever could find the end of the column would be judged supreme. Vishnu took the form of a boar and burrowed downward, deeper and deeper into the nether worlds, seeking the base of the fire ~ and failed to reach it. Brahma took the form of a swan and flew upward toward the top, up past the edge of the created cosmos ~ and failed to reach that too. Humbled, their pride broken, both returned and bowed before the pillar of light, which they now understood to be the source of them both, and of all moving and unmoving things.
Though you are in the form of fire, you have kept away the fire and have taken the shape of a hill, to shower your blessings on the people.
And here is the turn that makes Arunachala what it is. That infinite column of fire, the texts say, is Arunachala ~ but a fire so overwhelming that no creature could approach it. And so, out of compassion, Shiva cooled the column into the form of a hill: the same fire, the same presence, made gentle enough to be walked around, sat beneath, and loved. The hill you see is that fire, banked and made approachable. That is why it is worshipped as the mountain itself ~ not as a place where God is, but as the form God took.
Older than the gods who came to worship it
There is a strange harmony between what devotion says of Arunachala and what geology does. The tradition holds the hill to be primordial ~ older than the temples, older than the town, present before the ages of the world. And the geologists, in their own idiom, agree: the rock of Arunachala and the land around it dates to the Archaean era, roughly 2,600 million years, which places it among the very oldest exposed rock on the surface of the earth ~ older by far than the Himalayas, older than most of the ground we walk on anywhere.
Its presence in human record is old too. The region appears in the Sangam-era Tamil literature at the turn of the current era, where the lord of this land is called Chevvarainatan ~ from chevvarai, "the red hill." The hill is named directly, as Annamalai, in the sixth- and seventh-century hymns of the Thevaram, sung by the great Tamil Shaiva saints; the poet-saint Manickavachakar is said to have sung his Tiruvembavai on the pilgrimage path around it. For at least fourteen centuries, and almost certainly far longer, people have walked this ground and called it holy.
Why you walk around it, and do not climb it
If the hill is the body of the deity, then to tread upon its summit is a different thing from admiring a view. This is why the tradition asks pilgrims to walk around Arunachala rather than climb it. The central practice here is not ascent but circumambulation ~ Girivalam, the fourteen-kilometre walk around the base of the hill, keeping it always on your right, which is regarded as a direct and powerful act of worship of Shiva. Climbing to the summit is generally discouraged, and at times restricted. The caves on the lower slopes, where sages have long sat in meditation, are open to the pilgrim; the peak, by long custom, is left to the god. To go deeper into the walk itself, see our complete guide to Girivalam.
The legend and meaning above are drawn from the Arunachala Mahatmyam as published by Sri Ramanasramam in "The Glory of Arunachala," and from the ashram's own historical accounts. The mythology is retold here in our own words; the tradition itself, not this writer, is the authority. Where dates and details can be checked, they have been.
Frequently asked questions
What is Arunachala?
A sacred hill, about 800 metres high, at Tiruvannamalai in Tamil Nadu. In the Shaiva tradition it is revered not as a hill with a temple on it, but as a direct manifestation of Shiva in the form of fire ~ one of the five Pancha Bhuta Sthalams, representing the element of fire.
Why is Arunachala considered sacred?
The Arunachala Mahatmyam tells how Shiva appeared as an infinite column of fire to settle a dispute between Brahma and Vishnu, then took the cooled form of the hill to be approachable and to bless his devotees. The hill is therefore worshipped as Shiva himself, and walking around it (Girivalam) is a powerful act of worship.
How old is Arunachala?
Geologists date the rock to the Archaean era, roughly 2,600 million years ~ among the oldest on earth. It appears in Tamil literature from the Sangam period and is named in the 6th–7th century Thevaram hymns.
Can you climb Arunachala?
Because the hill is regarded as a form of Shiva, tradition holds that one should walk around it rather than climb it, and reaching the summit is generally discouraged and at times restricted. Pilgrims perform Girivalam and visit the caves on the lower slopes instead.
