Vaitheeswaran Koil: the Temple of the Divine Physician

Across the Cauvery delta of Tamil Nadu, temple towns follow one another like beads on a thread, each with its own presiding deity and its own reason for pilgrimage. A few kilometres from Sirkazhi, in what is now Mayiladuthurai district, stands one of the most singular of them all. Here Shiva is worshipped not as the great ascetic or the cosmic dancer but as Vaidyanathar — the divine physician, the god who heals. The town takes his name: Vaitheeswaran Koil, literally “the temple of the lord of medicine”, and for centuries the sick and the anxious have come to it seeking a cure.

The lord who is a physician

The name Vaitheeswaran fuses two words — vaidya, physician, and ishvara, lord — so the deity is quite literally “the lord who is a doctor”. Devotees come to the Vaitheeswaran Koil temple to pray for relief from illness of every kind, and the belief in the temple’s healing power runs through almost every shrine and ritual within it. His consort here is Thaiyal Nayaki, herself invoked as a healer, and the temple is also strongly associated with Murugan, worshipped as Selva Muthukumaraswamy, who is said in local legend to have received his vel — his sacred lance — at this very spot. Like the great Shiva temples at nearby Sirkazhi and Thiruvenkadu, Vaitheeswaran Koil is a Paadal Petra Sthalam — a shrine sung in the Tevaram hymns by the Saiva poet-saints, the Nayanars, as long ago as the seventh century.

Mars, healed of leprosy

Vaitheeswaran Koil is best known beyond the delta as one of the Navagraha temples — the nine shrines of Tamil Nadu, each linked to one of the nine celestial bodies of Indian astrology. This is the temple of Angaraka, the planet Mars, known in Tamil as Chevvai or Sevvai and in the north as Mangal. The link, fittingly, is a story of healing. By tradition, Angaraka was once afflicted with leprosy, and it was Vaidyanathar who cured him; ever since, the grateful planet has been enshrined here. The bronze image of Angaraka, shown riding a goat, is carried in procession on Tuesdays, the day sacred to Mars. Because of this, the temple has become the great destination for those advised that they carry a “Chevvai dosham” — a supposed affliction of Mars in the birth-chart, thought in astrological tradition to trouble marriage and health — who come here to seek its remedy.

The Siddhamirtham tank and the casting away of disease

At the heart of the complex lies the great temple tank, the Siddhamirtham — a name that means something like “the perfected nectar”. Its waters are held to be curative, and a dip in the tank is believed by devotees to wash away disease. Around it has grown a whole vocabulary of healing observance. Pilgrims dissolve jaggery in the water, an act traditionally said to relieve skin ailments; others place salt and pepper in a pot before the temple’s tall flag-mast, a gesture understood as casting one’s illness away. Perhaps the most distinctive of all is the Thiruchandu Urundai — small balls of sacred ash and soil taken from the temple, which the faithful swallow as medicine in the belief that they cure any ailment. None of this, of course, is medicine in the modern sense; it belongs to the long devotional tradition of a temple whose whole identity is bound up with the promise of a cure, and it is best understood in that spirit.

The town of the palm-leaf readers

For many visitors, the name Vaitheeswaran Koil calls to mind not only the temple but the town’s other, stranger fame — as a home of Naadi Jyotish, or palm-leaf astrology. Along the streets around the shrine work families of readers who keep bundles of olai chuvadi, dried palm-leaf strips inscribed in old Tamil script and attributed by tradition to ancient sages such as Agasthya. The readers hold that each leaf records the life of a particular person, foretold long ago, and that by matching a visitor’s thumbprint to the right bundle they can read out that person’s past and future. The practice has been passed down within hereditary families for generations and draws the curious from across India and abroad. It is, it should be said, a matter of faith and local custom rather than of proven fact — an old tradition of the town, best approached with an open and sceptical mind alike, and one whose fees and claims vary greatly from reader to reader.

Visiting

Vaitheeswaran Koil sits squarely on the delta’s temple circuit and is easily reached from Sirkazhi, Mayiladuthurai or Chidambaram, each a short drive away; it even has its own small railway station on the line through the delta. The temple keeps the usual pattern of morning and evening hours, closing for a few hours in the afternoon, and Tuesdays — sacred to Mars — draw the largest crowds. As at any Tamil temple, dress modestly, remove your footwear before entering, and treat the inner shrines with care.
